Guage

image.jpgI know this isn't a tool, but I'm not sure where else to seek advice. It is a massive brass duplex test guage by Shepard, Davies of Sydney. 175mm in diameter, machine turned mechanism and hand painted face. It weighs 5.5kg. The threaded coupling is stamped with 10/44, which I take to be date of manufacture. The J (broad arrow) B stamp I assume indicates a military connection. Any thoughts gratefully accepted.

Regard,

tim
