An English-made pocket altimeter-barometer, probably intended for military use and dating from the 1970s or 1980s. Quite large (80mm diameter) for a pocket barometer, in good working order, complete with its original leather case. Although not signed by Francis Barker & Son Ltd, this altimeter is in the style of instruments made by Barker in the 1970s and 1980s. There is a little wear to the bezel ring, but otherwise the altimeter and leather case are in excellent condition.
In very good condition and full working order. With some cosmetic wear and marks to the rotating bezel. The leather case is in very good condition. (Please note: this is a vintage instrument and should not be relied upon to give an exact reading, such as you might get from a modern digital instrument. However, it has been tested recently and is reading very accurately).
