Not sure if this is worth anything?

[gordon]

I have a high pressure gauge with fittings, is it worth anything ?.
I cant see any makers mark on it, but its ex Fire Brigade so wouldn't have been a cheap gauge when new .

0 to 400bar/ 6000psi

Worth about £10-£15 on auction sites

That appears to be a "fill pressure test rig".
To test/show what pressure a sub-surface cylinder (ie one without a gauge built-in to the valve) contains.

A useful thing to have if you own a sub surface cylinder & suspect it is not being fully filled by the shop.

Your proberbly correct , as it was used in the maintenance of FB breathing apperatus.

Thanks for the reply
