Quincy Air compressor ID.

[Crazy old geezer]

I have acquired a Quincy air compressor that has no ID tags . and It won't pump enough air to shut it off. The compressor was supposedly sent to Quincy 5-6 yrs ago for this problem and was supposedly fixed.
I need to identify it so I can get parts if needed Photos attached. Any help will be greatly apperciated .

Are you running it as pictured with no tubing to the unloaders? If so, that's the place to start.

You are missing the caps beside the unloader towers too.

Looks like a 216. They don't put out a lot of air once they hit 100psi. If you are trying to get 150 or 175 out of it you will be frustrated. You might be able to find pipe caps that fit those uncovered valve retainer rings.
