Compensated for temperature fluctuations, this late 19th century pocket barometer incorporates an altimeter scale from zero to 18,000 feet, indicating it was constructed for use at high altitudes probably by hot air Balloonists or Mountaineers.
The barometric scale is contained within a rotating bezel and reads from 16 to 31 inches with all the lettering and numbers etched into the clean silvered dial.
In good condition the case is made of gilded brass and is dent free, with the majority of its gilding intact, although some minor loss on the sides.
It comes with its original silk a velvet lined leather case which is also in good condition with both the hinge and catch in working order.
Measuring 50mm in diameter and 20mm in depth, it's in good working order passing the bag test with the needle rising and falling under pressure as it should.
Although unsigned, pocket barometers with altimeters of such a high altitude were often made to order for individuals and don't come along too often.

This turn of the century pocket barometer and altimeter is signed 'FRANKLIN.HARE & GOODLAND Ltd, TAUNTON', and housed in a gilded brass case.
Compensated for temperature, the clean silvered dial has a barometric scale ranging from 23 to 31 inches with a rotating altimeter scale for altitudes up to 8,000 feet and is in good working order, with the needle rising and falling under pressure.
It comes with a 19th century Black Forest pocket watch stand holder, superbly carved with acorns and the name FREIBURG, the city commonly known as the capital of the Black Forest. Although the stand and barometer were made at different times they are a good fit, making a combination that works well as a display.
Both items are in good cosmetic condition, with the barometer only having some gilding loss in places, and the wooden stand having a minor age crack on the top left, plus the odd inactive worm hole. These are minor defects I mention only for accuracy and do not impact on the functionality of the barometer, nor the aesthetics of the stand.
Together they weigh 160 grams, with the stand measuring 115mm long closed and 110mm high when displayed.

This is a quite unusual aneroid wall barometer, in that among the normal forecasts one expects to see on an aneroid barometer, is the word 'Hurricane'.
Dating to the latter part of the 19th century, it is signed 'LENNIE EDINBURGH - Compensated' on the dial, this refers to Eliza Lennie who succeeded her optician husband James Lennie who died in 1854.
Set in an attractive turned oak surround the etched decorative silvered dial sits under a clean bevelled glass held within an anodised brass bezel and includes a hanging bracket attached to the underside.
Compensated for temperature and in good working order it weighs just under 1.15kgs, measuring 7¾" (195mm) diameter overall, with a bezel diameter of just under 6" (150mm) and 3" in depth.
In excellent condition, the passage of time has produced a warm patination on the oak surround which is free of any splits or cracks.

This ingenious invention first patented in 1915 by Negretti & Zambra, is designed to accurately predict the weather in conjunction with wind direction & barometer readings, which are then set by two rotating discs, revealing a letter code corresponding to one of 26 forecasts printed on the reverse.
Whilst copies are now available, this is the genuine article carrying the Negretti & Zambra London name and patent no 6276/15.
It dates to the 1920's & comes complete with it's original instructions inside a Negretti & Zambra branded red leather pouch embossed in gold lettering 'Negretti & Zambra'.
Measuring just 55mm in diameter & of ivorine construction it's in very good complete condition and with a reportedly 90% accuracy.

One of the leading optical instrument makers of 19th century England, Thomas Cooke supplied members of the royal family, and in 1850 produced the largest telescope in the world at that time, which is now housed in York Observatory.
This particular barometer was made after his death, by his sons shortly after the company opened a Cape Town office in 1899 and is signed 'T. COOKE & SONS Ltd. LONDON YORK & CAPE TOWN. No.722' on the dial.
This compensated barometer was probably made for the contintental market as the dial is calibrated for Torr, a unit of pressure based on an absolute scale, defined as exactly 1/760 of a standard atmosphere, and this dial has a scale range of 41 to 79, equivalent to approximately 16 and 31 inches of mercury. It also has a rotating altimeter measuring from 0-5500 metres. It's described as a cylindrical aneroid barometer in T Cooke & Sons catalogues of the early 20th century, and would have had a variety of uses including surveying.
In good working order, the dent free bronzed brass casing retains much of its original finish, and although the glass crystal has some minor edge chips, there are no cracks and is still sound.
A substantial instrument, it measures 115mm diameter not including the stem, by 53mm in depth and weighs just over 1000 grams and 1200 grams in its leather case, which is also in good condition despite a reglued locking strap.

This impressive antique wall mounted aneroid barometer is set in a polished oak surround and features a curved fahrenheit thermometer on a distinctive aluminium dial in very good condition, and engraved 'NEGRETTI & ZAMBRA, LONDON. 11261'.

Dating to the early Edwardian period around pre WW1 period, it's in good working order, including the thermometer.
Barometers by Negretti & Zambra are much sought after and this is a substantial yet decorative piece, weighing just under 1.4kg, with dimensions of 8¼" (210mm) diameter at the base, a 4 ½" (115mm) dial, and a depth of 2 ¾" (70mm).

Please note, due to size and fragility, this item is only available for delivery to a UK address.

This is a very elegant aneroid pocket barometer with a decorative enamel face, made in London during the early part of the 20th century.
A visually striking barometer, it's a nickel or silver plated Goliath model which is larger than most pocket examples and measures 65mm in diameter, not including the stem or suspension ring. It comes in a green silk & velvet lined leather display case with a hammered solid silver cover hallmarked Chester, along with the letters HM which I believe may be for Henry Matthews of Vittoria Street, Birmingham. The date letter is a little too rubbed for me to identify clearly, but may be easier for silver collectors, (see photo) The barometeric scale ranges from 26 to 31 inches with the lettering and numbers in raised print on a very clean, white enamel dial, it also has a rotating bezel with a small guide marker to set the last measurement. In full working order and in good cosmetic condition, the case measures 110mm x 105mm, has a fold away strut on the back for desk display and weighs less than 300 grams with the barometer in situ.
Please note the inner velvet holding ring has stretched a little over the years and some felt has been added to better keep the barometer in place.

In very good condition all round with the barometer retaining much of its original gilding, a collectable antique instrument that is still practical for use today.

Collectors of Negretti & Zambra instruments will recognise the rarity of this box model version of the famous weather forecaster.
Dating to circa 1915/20 when the ‘weather forecaster’ system was patented, a number of variations were produced and this particular model was made in much smaller numbers than the circular brass or celluloid examples, hence its comparative rarity.
As with the other weather forecasters, it’s designed to more accurately predict the weather in conjunction with wind direction & barometer readings, which are then set by the two rotating discs, in the upper half, revealing a letter code in the appropriate window, which will correspond to one of the 26 forecasts printed on a rotating drum, and operated by a knob on the side.
Made from a black metal casing this particular example has an ivorine faceplate instead of the usual brass type which makes it even rarer.
In exceptional condition, it’s signed ‘NEGRETTI & ZAMBRA, LONDON’ on the faceplate with the inter-twined NZ logo and the patent no 6276/15
Weighing just under 400 grams, it stands just over 5.5” high, 3” wide, and there is a keyhole slot in the back making it suitable for hanging on a wall or standing on a desk/table/mantelpiece.

Measuring 52mm diameter x 18mm depth, it weighs just over 125 grams in its case and is in good working order, including the Fahrenheit thermometer.
Although unsigned, this is quite a rare instrument of quality that is still practical for use today.

This 19th century pocket barometer was awarded to Sub-Lieutenant Charles Langdale Ottley as a prize for passing the best examinations at the Royal Naval College Greenwich, in 1879.
Following a distinguished career in the Royal Navy, he later went on to become Rear-Admiral Sir Charles Langdale Ottley, Knight Commander of Most Distinguished Order of St Michael and St George, Member of the Victorian Order.
The inscription on the reverse of the barometer reads 'Presented by The Lords Commissioners of the Admiralty TO SUB LIEUT: C. L. OTTLEY For meritorious Examination 1879'
Born in 1858, Ottley joined the Royal Navy in 1871 serving as Torpedo Lieutenant in 1884 aboard the training vessel H.M.S. Vernon and later the same role aboard the ill fated H.M.S. Victoria in 1889, then the most powerful battleship on the planet, that served as flagship to the Mediterranean Station before its accidental sinking in 1893.
Ottley was awarded the rank of Captain in 1899 before being made Director of Naval Intelligence in 1905 and secretary to the Committee of Imperial Defence in 1907, finally being placed on the Retired List with permission to assume the rank of Rear-Admiral in 1908.
Made by Elliot Brothers, the silvered dial reads 'Compensated Elliot Bros. 449 Strand, LONDON. 2578.', with a barometric scale measuring 21 to 31 inches, and includes an altimeter scale for altitudes up to 10,000 feet.
All lettering is clearly etched onto the dial which is housed under a domed glass crystal with beveled edge.
Measuring 50mm diameter x 22mm depth, it weighs just under 130 grams in its case, and although the dial has some noticeable surface scratches it is in good working order. Please note also the trend pointer pin on the rotating bezel is present, but shortened having lost the tip at some point in the past (see photo).
A quality instrument with an interesting provenance belonging to a distinguished officer of the Royal Navy.

The aneroid barometer was invented in 1843 by the French physicist Lucien Vidi, who held the patent rights until 1855.
Despite the invention being ground breaking, Vidi had trouble distributing these barometers to the French market and travelled to London sometime after 1845, where he persuaded Edward John Dent, the premier clock maker of the 19th century, who would later be commisioned to construct the Great Clock of the Houses of Parliament in Westminster, to sell in Britain an initial amount of 5000 on his behalf.
This particular example is inscribed 'E. J. DENT, Paris' and has the early serial number of '833' showing it to be part of the original batch of 5000, which would likely date it to the late 1840's or earlier. (The earliest dated example of this barometer in the London Science museum is numbered 296 and dated to 1846.)
In full working order (easily passes the plastic bag test), the barometeric scale ranges from 28 to 31 inches and incorporates a curved Fahrenheit's thermometer from 20 to 120 degrees.
In very good condition with a clean glass crystal and crisp lettering on the silvered dial, it's housed in a brass case retaining much of its original lacquer, and curiously has the inscription 'Z. 9', on the reverse.
Measuring 120mm in diameter by 40mm deep and weighing just over 530 grams, this is a rare opportunity for serious collectors to buy one of the very earliest Vidi barometers from the first 5000 made, which had the original dial design where the forecasts are above the barometric scale, in contrast to below on the later models.

This pocket barometer with altimeter scale is inscribed 'NEGRETTI & ZAMBRA, LONDON 12421' and dates to the latter part of the 19th century.
Housed in a gilded brass case which is in good dent free condition, the dial sits under a clear bevelled crystal, which in turn is held within the crown operated rotating bezel containing the altimeter.
The barometric scale ranges from 21 to 31 inches with an altimeter scale ranging from zero to 10,000 feet, suggesting it was made for use at relatively high altitudes, and all lettering and numbers are etched on the silvered dial.
It comes with its original velvet and silk lined leather covered rounded edge case, which is also in good condition with both the hinge and catch in working order, the interior lid is also stamped 'NEGRETTI & ZAMBRA, LONDON' in gold lettering.
In good cosmetic condition retaining most of its original gilding, the only blemish being a minor edge chip on the glass crystal and bezel, which does not affect the function, (see photo).
Barometers by Negretti & Zambra are much sought after, and this is a fine example in full working order (it passes the plastic bag test), measuring 50mm diameter and 18mm in depth it weighs just over 120 grams in its case.

This pocket barometer is signed 'F. WESTLEY, 27 Old Bond St, LONDON' and probably dates to no later than 1870, which is when this particular maker of whom very little is documented, ceased trading having been established in 1850.
The case is made of polished brass and in very good condition, with no denting and only minor wear.
The barometric scale reads from 22 to 31 inches and all the lettering and numbers are etched into the frosted silvered dial set under a clean crystal.

At over 150 years old this is a nice example of a quality barometer, by one of the lesser known makers of the time.

Mostly based in the Hatton Garden and Holborn areas of London, the Somalvicos were a well-known London family of instrument makers who specialized in barometers in the 18th and 19th centuries and were known for making high quality barometers and other instruments.
This Edwardian pocket barometer and altimeter is signed 'JOSH.SOMALVICO& CO. 18 CHARLES ST. HATTON GARDEN LONDON E.C.' and was made by Joseph Somalvico, a third generation instrument maker whose Grandfather Joseph emigrated from Italy to England in the last quarter of the 18th century, and is credited with the introduction of the dial form mercury barometer.
Housed in a dent free polished brass case, the silvered dial has a barometric scale reading from 23 to 31 inches and set under a clear crystal, which in turn is held within the crown operated rotating bezel containing the altimeter scale of zero to 8,000 feet.
In full working order, it comes in the original Moroccan leather case which is also in good condition, with a sound hinge and catch, and green and brown velvet interior.
A fine antique instrument from a well regarded maker, in good cosmetic condition and weighing just over 120 grams in its case, it measures 52mm in diameter by 18mm deep.

This ingenious invention first patented in 1915 by Negretti & Zambra, is designed to accurately predict the weather in conjunction with wind direction & barometer readings, which are then set by two rotating discs, revealing a letter code corresponding to one of 26 forecasts printed on the reverse.
Whilst copies are now available, this is the genuine article carrying the Negretti & Zambra London name and patent no 6276/15.
It dates to the 1920's, and this particular example was made specially for retailing by J Lizars with both the original instruction leaflet and box stamped 'LIZARS ABERDEEN'
Measuring just 60mm in diameter and of ivorine construction it's in excellent complete condition. 

This pocket barometer with altimeter is inscribed 'COMPENSATED - G.W.Strawson LONDON' who operated out of 15 Percy Street, Tottenham Court Road London in the late 19th and early 20th centuries, making optical, meterological and mathmatical instruments.
Housed in a gilded brass case which is in good dent free condition, the dial sits under a clear domed and bevelled crystal, which in turn is held within the rotating bezel containing the altimeter scale.
The barometric scale ranges from 21 to 31 inches with an altimeter scale from zero to 10,000 feet, suggesting it was made for use at high altitudes, and all lettering and numbers are etched onto the silvered aluminium dial.
In full working order (it passes the plastic bag test) with the needle rising and falling under pressure as it should, the brass casing retains much of its original gilding, save for some minor tarnish on the underside.
Interestingly, there is some writing on the lid interior which appears to be records of a previous owners mountaineering activities, and although much is faded and difficult to read, one that can be made out relatively clearly is Pilatus 6900 (see photo), which likely refers to Mount Pilatus in Switzerland with a summit of over 7,000 feet.
Measuring 50mm in diameter not including the stem, 20mm in depth, it weighs just over 130 grams in its original leather case, which is also in good condition, with a solid hinge and working catch.

A nice example of a late 19th century unsigned antique pocket barometer compendium, which includes a circular centigrade thermometer and a small cross bar needle compass.
On the opposite side is a traditional clean silvered dial barometer with a barometric scale ranging from 21-31 inches and an altimeter scale for altitudes up to 10,000 feet.
This is housed in a 3 section leather over wood outer case with green silk and velvet lining the interior, the central section securing the combination in place for viewing either side.
All in full working order, the barometer passes the plastic bag test with the needle rising and falling under pressure, and the thermometer adjusting to temperature as it should. The compass needle spins freely to find North which can also be held in place using the manual transit lock when closed.
Probably intended for mountaineering or hill walking activities, it measures 48mm in diameter by 25mm in depth, and weighs just over 150 grams with the outer case.

A much rarer version of the popular Negretti & Zambra celluloid pocket weather forecaster, this being a wall or desk model measuring 120mm in diameter, and made from brass.
Dating from around 1920, this is a larger and more comprehensive forecaster, giving 60 forecast lines, and also a more decorative piece.
It carries the same patent number 6276/15 and consists of a circular frame with two rotating discs which set the barometric pressure, wind direction and rise or fall.
The main center disc also has all the directions for use engraved on it, and is in good condition with all the text legible.
Measuring 120mm in diameter and weighing 320 grams, it comes with a modern copy of the instruction leaflet.
Not only still practical today with a reportedly 90% accuracy, it also displays very well, either on the wall or free standing on its integral stand.

During the 19th century, barometers were vital instruments on board ship for predicting weather conditions, specifically registering direction of pressure changes.
This particular marine barometer, made to accompany a ships chronometer, is quite a rare example as the trend pointer is rotated by an internal mechanism operated by a removable brass key, which would likely have been retained by the Captain or other officers.
Dating to the last quarter of the 19th century, this barometer is signed 'CALLAGHAN & CO. 23a New Bond St. Corner of Conduit St LONDON'.
Formerly an apprentice of Thomas Harris & Son, William Edmund Callaghan founded his own Opticians business in 1860, specialising in barometers, optics and other meteorological instruments. Later changing names to 'Callaghan & Co' in the early 1870s placing this piece to around that time.
Set in a turned oak surround, the barometric scale ranges from 28 to 31 inches with the lettering and numbers printed on a clean ceramic dial under a clear bevelled glass within a brass bezel.
Weighing just under 1.4kgs, a quality barometer in good working order, it measures 8" overall diameter, with a 5" dial diameter and 2½" depth.

A very rare desk model aneroid barometer made at the height of the Art Deco 1930's period, it's signed ZEISS IKON, BERLIN, on the front glass.
This particular example is in excellent cosmetic condition as can be seen from the Photos with only very minor spotting in the chromium plating.
It stands 6¼” high, with two scales 960 to 1070 milibars and 28.4 to 31.6 inches, arranged in a semi-circle clearly printed on the inner surface of the front frosted glass.
The indicating & set pointers are behind the scale in front of a frosted glass background, and the paper operating instructions printed on the underside of the base are a modern copy as the original was missing, but still covered with the original clear celluloid disc.
Dating to around 1935, it really is a stunning piece and particularly suitable for any art deco collection or theme.
In good working order and weighing just under 650 grams, it passes the plastic bag test with the needle rising and falling under pressure, but as with all barometers of this age would need calibrating for optimum accuracy.
These were made in small numbers, so this represents a unique opportunity to buy a rare barometer that really does not come along very often.

This is a late 19th century pocket barometer and altimeter which unusually incorporates a miniature floating dial compass inset in the dial.
Made by and signed ‘CALLAGHAN & Co, 23 New Bond St, LONDON’ around 1890, the clean silvered dial has a barometric scale reading from 19 to 31 inches, with an altimeter range of minus 1,000 feet to 11,000 feet. This would suggest it was designed not just for height readings, but also for measuring air pressure in mines, where changes in barometric pressure can create safety risks.
Measuring 47mm diameter and 16mm in depth, it’s in good working order with the needle moving smoothly under pressure and the small compass finds north consistently. The gilded brass case has lost some gilding on the underside, but is in good dent free condition.
Not only is the design of this barometer uncommon, but the cosmetic condition is also good with a clean chip free bevelled crystal, it also comes with the leather covered outer case which has a working catch and button.

Dating from the last quarter of the 19th century, this is a nice example of a brass compensated pocket barometer and altimeter with a curved Fahrenheit thermometer.
The case is made of polished brass and in very good condition, with no denting and only minor wear.

Collectors of Negretti & Zambra instruments will recognise the rarity of this box model version of the famous weather forecaster.
Dating to circa 1915/20 when the ‘weather forecaster’ system was patented, a number of variations were produced and this particular model was made in much smaller numbers than the circular brass or celluloid examples, hence its comparative rarity.
As with the other weather forecasters, it’s designed to more accurately predict the weather in conjunction with wind direction & barometer readings, which are then set by the two rotating discs, in the upper half, revealing a letter code in the appropriate window, which will correspond to one of the 26 forecasts printed on a rotating drum, and operated by a knob on the side.
Made from a black metal casing it has the original silvered face plate which retains most of it's finish, and all the engraved characters and forecasts are clearly legible.
It’s signed ‘NEGRETTI & ZAMBRA, LONDON’ on the face plate with the inter-twined NZ logo and the patent no 6276/15.
Weighing just under 500 grams, it stands just over 5½” high, 3” wide, and there is a keyhole slot in the back making it suitable for hanging on a wall or standing on a desk/table/mantelpiece.

After working for Queen Victorias appointed opticians Gardener & Co in Glasgow for nine years, James Brown set up on his own in 1871 at 76 St Vincent street Glasgow, where he made and stocked a variety of instruments including pocket barometers, along with barographs and larger mercurial barometers.

Twyford school near Winchester is one of the oldest Prep schools in the country having been formed in 1787, and had a number of distinguished Headmasters throughout the 19th century. This particular pocket barometer was given as a gift in 1876 by one of the longest serving Headmasters, Reverend Latham Wickham to a George Herbert Evans, and is inscribed as such on the reverse.
Rev'd Latham Wickham born in 1833, was headmaster of Twyford School for 25 years from 1862 to 1887 and there is quite a lot of information about his achievements, including the creation of a proper cricket ground, as well as building the school chapel in 1869. Unfortunately I've not been able to identify who George Herbert Evans was, nor the occasion for the gift.
The barometric scale reads from 17 to 31 inches with all the lettering and numbers etched onto the clean silvered dial.
As the development of pocket barometers progressed rapidly after the 1870's, more advanced models were made with altitude scales far in excess of the standards of the time, and were primarily intended for use in balloonist & mountaineering activities.

It has a barometric scale range from 26 to 31 inches, in addition to an altimeter scale ranging from zero to 5000 feet.
The case is made of gilded brass and in very good condition, with no denting and most of its gilding intact, although there are some small roman numerals lightly scribed near the stem (see last photo).
A nice clean pocket barometer with a chip free beveled glass, it's in full working order, (it also passes the plastic bag test), and measures 45mm diameter by 16mm in depth.
It comes with its original silk and velvet lined case in very good cosmetic condition, with both hinge and catch in working order.

This ingenious invention first patented in 1915 by Negretti & Zambra, is designed to accurately predict the weather in conjunction with wind direction & barometer readings, which are then set by two rotating discs, revealing a letter code corresponding to one of 26 forecasts printed on the reverse.
Whilst copies are now available, this is the genuine article carrying the Negretti & Zambra London name and patent no 6276/15.
It dates to the 1920's, and comes complete with its original instructions inside the N & Z cardboard box.
Measuring just 60mm in diameter and of ivorine construction it's in good complete condition, and with a reportedly 80% accuracy if you have a barometer you need one of these! 

This 19th century brass cased aneroid barometer is engraved 'LANDER TRURO', and I believe was probably made as a commemorative piece for the famous 19th century explorer Richard Lemon Lander who was born in Truro, Cornwall in 1804.
Lander along with his brother were the first Europeans to follow the course of the River Niger between 1830 and 1831, establishing that it led to the Atlantic which greatly contributed to development of trade links between Africa and the rest of the world.
Following his early death in 1834, Lander was celebrated as a local hero in Truro, where in 1835 a sculpted memorial monument was built in Lemon Street, which still stands today, as well as naming the local secondary school after him.
You can find more details about Richard Landers fascinating life of exploration here: The Richard Lander Story.
In good condition all round, the brass case is dent free and the clean silvered dial has a barometric scale ranging from 28 to 31 inches.
Weighing just over 750 grams and measuring 120mm in diameter by 46mm in depth, it's in good working order, including the curved thermometer which has an unbroken line.

An impressive early 20th century surveying aneroid barometer & altimeter signed 'Short & Mason London, Compensated, No J6646'.
This is a large precision instrument measuring 125mm in diameter and weighing just under 1.2kgs, and designed for use by both surveyors & mining engineers.
Compensated for temperature, the stepped outer silvered scale is calibrated in barometric inches ranging from 28 to 31, and altitudes to 3,000 feet.
In full working order, and with only some paint loss on the brass body, it's in very good cosmetic condition including the original fitted leather case.

This is a nickel pocket barometer/altimeter with curved thermometer signed 'J BATEMAN 131 High Holborn' on the dial.
Dating to between 1860 to 1870, the unusual barometer case design is very similar to that used by Thomas William Watson so it's possible he was the maker, albeit it was retailed by John Bateman who was described as a mechanical engineer and model ship builder.
The frosted silvered dial is clean and has a barometric scale range from 23 to 31 inches, in addition to an altimeter scale ranging from zero to 8000 feet.
The case is lined with green velvet and silk and is in very good condition all round, with a moroccan leather skin and working catch that snaps shut when the lid is closed.
In full working order including the thermometer, the barometer measures 45mm diameter and 18mm depth.

Whilst silver hallmarked pocket barometers are uncommon, this particular example is even more so given its only 35mm in diameter. Compared to its larger counterparts at 48mm in diameter makes this a much more collectable piece, (see Photos for comparison).
Made by instrument maker and optician Joseph Rankin Stebbing, the son of George Stebbing, he worked in Southampton from 1831 until his death in 1874.
A prominent figure in the city he also held the office of first President of Southampton's Chamber of Commerce and later Mayor.
Signed 'STEBBING & CO - SOUTHAMPTON' on the aluminium dial, with a scale range from 25 to 31 inches, it's London hallmarked on the bow with the date letter 't' which I believe is for 1874, so probably one of the last pieces made before his death.
In good cosmetic condition overall, the dial does have some minor surface marks but the case is free of any dents.
It comes with a 12" stylish Albert chain and T bar that would have been used for attaching to a Victorian gentlemans waistcoat, and is in good working order responding well to a plastic bag test.
