Short & Mason

The London firm, founded in 1875 by Thomas Short and James Mason,  was engaged in the production of quality aeronautical and meteorological instruments, including aneroid barometers. In 1907 (according to other data 1900) it was taken over by the still existing American company Taylor Instrument Companies, which from 1851 was  producing devices for measuring and regulating temperature and pressure. The Short & Mason brand ceased to exist in 1969.
