Found this PC at a thrift store.
Even tho it has a gauge, can anyone tell me if it needs a rattle weight too?
When I try to bring up the pressure, the pin in the valve on the left starts popping up and releases steam, so that pressure never builds.
If I hold the pin down, then the pressure gauge actually starts to move and build pressure, but as soon as I stop holding the pin in, it pops up, all the steam releases and the pressure goes back to zero.
Pretty sure that is the petcock on the right. It can be unscrewed to release pressure.
There is also a bolt kinda thing a couple inches behind the gauge (can't see in pic), it doesn't have any holes, moving parts. What is this thing? Old style emergency release valve? Like if pressure builds too high then this thing shoots into my ceiling like a bullet?
Also wondering if these parts can be replaced with more modern aa/mirro/presto parts?

That part may be broken. Try a shot glass over it or a nail in the hole. Don't worry, nothing is going to shoot out. You'd need a lot of pressure to make it shoot but as soon as there is enough to move it, it'll just fall over. You'd have to delibertly hold it in there while the pressure built in order to make it shoot. It simply doesn't happen...been there...done that...

That's identical to mine. The safety valve on the left relieves pressure with a small puff every now and then. Nice find..

You're good to go if the guage works right and it doesn't leak when pressure is built up...

Does yours have a spring in it? If you tried to pull the pin up is there resistance?
Mine doesn't relieve pressure with a small puff out of that valve, it starts releasing it as soon as it builds up.

Yeah, it should have a spring the goes around that small rod that sits on the ball bearing.
