This very fine late 19th c. Gilded and leather cased pocket barometer / altimeter was made by the prestigious Viennese firm of Otto Schlieffelder and is marked on the face: OTTO SCHLIEFFELDER / IPTIKER / WIEN / GRABEN 29. The dial is also marked COMPASIRT. The barometric function of the instrument and is market on the inside fixed dial and divided with the words REGEN and SCHON with a range between 49 and 79. The altimeter is scaled on a sliding venier and is accurate from 0 to 4000 meters (it could well have worked for most mountain climbing in the Alps). The reverse has an adjustment screw. This gilded brass instrument is in a fitted deep purple hinged hard shell leather case lined on one side with purple velvet and on the other with purple silk. The case is fitted with a brass locking tab and a probably replaced thumb piece for opening (it is a bit stiff but functions smoothly). The overall size of the case is 2 3/8″ in diameter and about 1 1/8″ thick. The barometer/altimeter is 1 7/8″ in diameter and is 5/8″ thick. I have been checking he barometric function of this piece and it appears to function (I have noted travel of the needle on the dial). Chances are it needs some adjustment with the screw on the back to set it with a known barometric reading. This piece is in excellent overall condition with no dents scratches or other damage. The case is only lightly worn. The item “Leather Cased Gilded Pocket Barometer/Altimeter-Otto Schlieffelder, Vienna c. 1890″ is in sale since Saturday, June 1, 2019.
