That pressure pot looks like it came off the Ark! Was the guy you bought it off's name Noah?
It looks like a regulator to me, so turning the knob will adjust the pressure it will fill to [OK, just re-read your post and you know that but are just calling it a different name]. And if it's letting out a stream of air then it does indeed sound broken. IIRC some of the fittings on my pot were metric and thus a pain to adapt to, but like I've mentioned before specialist air equipment shops (NOT gas or plumbing) should be on the ball with it.
Bec's suggestion is a good idea: unscrew the knob all the way and it should eventually come out (there will be a spring and stuff in there so be careful). Take a look to see if it's all ok - judging from the state of the rest of the pot perhaps the spring has rusted away?
Oh yeah I can make that....
