Antique Short & Mason Pocket Barometer / Altimeter for A&ncs

Antique Short & Mason pocket barometer / altimeter for A&NCS.

The barometer is in beautiful condition, as though it has hardly ever been used. It has a gilt finish which is in super condition, just very light marking to the back. 50mm diameter excluding the stem and loop.

The glass lens is in excellent condition too.

The dial is signed with the name of the manufacturer, Short & Mason, London, a prestigious precision instrument manufacturer, founded in 1845 by Thomas Short and James Mason at Hatton Garden, London. As well as retailing their instruments, they supplied famous explorers including scientific instruments for the ill fated Scott and Shackleton Polar expeditions.

The dial is also signed A&NCS Ltd, which was the Army & Navy Co-Operative Ltd. The Co-Operative was founded in 1871 with a view to supplying members with goods at reduced prices. The membership was reliant on serving within the British military, or being part of a military family.

The outer chapter ring on the dial is marked from 0- 8,000 feet and indicates the height above sea level. The inner ring is marked from 23 to 31 inches and indicates atmospheric pressure in inches of mercury,

To measure your height you rotate the outer chapter ring until the hand is aligned with the zero (assuming you are at sea level), then as you climb, the hand moves due to the fall in air pressure and you will be able to read off the height you have reached.

The barometer automatically adjusts the reading for changes in temperature, thereby giving a more accurate reading. The altimeter is functioning although has not been tested for accuracy.

The barometer comes in its original Moroccan leather case complete with original tag.
