These antique aneroid instruments may be considered scarce.  Few survive, and this Darton altimeter remains in ‘as found’ original condition – sensitivity and transition remain excellent. It is most likely that the War Department issued this to the Army as opposed to the Royal Navy, with possible users being the Royal Engineers. A fine original instrument for the collector.

Banfield, Edwin, Barometer Makers and Retailers, 1660-1900 records Francis Darton & Co as working from various addresses in London from 1834 onwards, and the company existed up until the 1990s.
