Very large and pretty Hopkinson pressure gauge
 

Ive got a large Hopkinson pressure gauge it is marked from 0 to 20 PSI only.
I should imagine it would make a very nice time clock for somebody's workshop.
Solid brass construction with beveled glass face. 10 inches across approximately
£50 plus postage if required.

Pm or call 07833383700 for pictures
