Pocket barometer altimeter having 1¾” silvered and struck dial with outer scale from 0–10,000ft, the inner scale calibrated in inches of mercury with a range from 21–31″, the upper portion marked with standard meteorological wording “Rain, Change, Fair” and “Compensated,” the lower portion signed by the retailer “J. Hicks, Maker, London” and serial no. “5348.” Very fine blued steel pointer set beneath bevelled glass, maintained within a rotating bezel with index.
High quality and substantial movement driven by a single 1¼” capsule, bimetallic temperature compensation strip. Housed within a drum form case with engine turned bezel ring, suspension pillar and bow, the verso with compensation adjustment port and screw to 4 o’clock. The whole contained within its leather over wood, imperial purple velvet and champagne silk lined travel case. The verso engraved “Preston Maxwell.”
The lacquered brass case retaining almost all original finish with very minor marks to verso. The dial in excellent condition. The travel case in very good sound condition with very light wear to bottom and loss to leather over the button.
This is an early and very good quality pocket barometer altimeter in original condition. Although signed by Hicks, it is almost certainly the work of the world renowned instrument maker, Ross of London, who made instruments for sale to third party retailers. Serviced and calibrated, it works well and responds with good sensitivity.
