Pocket barometer compendium having engraved and silvered 1¾” dial, the upper portion marked “Compensated,” the lower portion marked with the maker “Negretti & Zambra, London” and serial no. “10772.” Outer rotating altitude ring having a scale in feet set from 0 – 10,000, barometric scale set to inches of mercury with a range from 21 – 31. Fine blued steel pointer. Coil-spring pattern single 1¼” capsule driven lacquered brass movement with decorated chassis.
Three piece drum form case with ribbed detail, knurled barometer bezel, suspension ring, calibration port accessed with compass detached. Detachable push fit magnetic compass, mother of pearl Singer Patent design dry card with cardinals and intercardinals, lyre motif to north, jewelled suspension, transit lock.
The whole contained within its original chestnut crocodile skin over wood brown velvet lined drum form case. Snap closure on button release.
A really good example of these now increasingly hard to find compendia, an instrument of obvious high quality and unusual in having a much larger than usual and heavily padded travel case constructed of very expensive materials. The barometer altimeter with good sensitivity and progression, working well; the compass swinging freely, easily finding north.
Retaining almost all its original lacquered finish, with slight loss to suspension loop, the compass card blemish-free, the crystals chip-free and almost perfect, the leather case in wonderful condition with good colour and integrity, the velvet lining sound.
An unusual and very attractive item, very collectable.
