Excellent example of pocket barometer, altimeter and compass compendium made in England The barometer scale goes from 21-31 inches and the altimeter scale ranges from zero to 10,000 feet adjusted by a knob. The wonderful and rugged compass has a nicely ornated dial and is attached to the back of the barometer. The body of the device is made from gilded brass with minimal wear and tear. Dimensions : 50 mm diameter and 24 mm height. The device is still showing differences in the barometric pressure and altitude variation, the compass hand moves freely but is not that accurate.
