This vintage brass pressure gauge would have originally been used in an industrial factory, to measure one pound-force applied to an area of one square inch.
The gauge is marked from 0 to 2000 and the dial bears the manufacturers name: Humphreys & Glasgow Limited.
Humphreys & Glasgow was established in London in 1872, for the erection of water-gas plants and apparatus which have been installed all over the world.
This is an authentic vintage brass pressure gauge, with a nice aged patina, but does bear marks consistent with its age and use.
Collect different sizes and finishes of pressure gauges and mount them on a wall in a bathroom, or office to create a visual impact. Five or seven work best!
Dimensions: 15 cms w x 4.5 cms d x 19 cms h
