Antique Silver Pocket Barometer Altimeter c.1893

This is a fine silver aneroid pocket barometer altimeter to 15000ft with movement by Elliott Brothers c1893. Silver pocket barometer having 1¾” silvered and engraved dial with dual concentric scales, the outer altitude scale calibrated in feet from 0 – 15,000ft and divided to 100ft, the inner barometric scale calibrated in inches of mercury with a range from 18–31”, divided to 1/10ths. The upper part with standard meteorological terms and “Compensated.” Rotating bezel with index, blued steel pointer, bevelled glass. Conventional first quality 1” capsule driven movement tensioned on a C spring. All contained within a barrel form case with engine turned finishers. The verso with calibration port, and full hallmarks for sterling silver, London, 1893, and the silversmith “J.S & S.” Extension post and suspension ring, hallmarked. Comments: This is a very good instrument - the quality is first class, the movement from Elliott Brothers, and the case evidently by a silversmith of status, though at this time the identity of “J.S & S” is unknown - the usual resources carry this hallmark, but do not specify the silversmith. Fine and working well, this silver pocket barometer would be a perfect gift or sit well in a collection.
