Antique Pocket Altimeter Barometer British Military Arrow Vintage

Description

This auction is for a vintage British pocket barometer altimeter. Approx. 2 11/16 inch case diameter and has the "broad arrow" mark indicating English military use. Decent vintage condition with case scratches and wear but just the one dent on the back edge that is shown in the last auction photo. Front outside ring rotates. Some spotting on the front face. Seems to be working, responds to the internet "sealed squeezed baggy" test but actual accuracy is unknown. Marked "TW s.i. Ltd." Exact era is unknown but probably WW1?
P
lease be sure to look at all of the enlargeable images to determine exact condition, application, and completeness.
