Have this ancient 220V compressor that came with the house and I am trying to figure out exactly what it is, or is it a hybrid of parts?

Jacuzzi Brothers Twin of unknown HP
Manchester Tank with data plate showing 1973
A.O.Smith AC motor of unknown HP
Tag on tank showing Sears Unit 1315 ACO-05

The previous owner used it in the recent past for painting projects.

It started right up as soon as I flipped the lever.

Ran beautifully and ran all the way up to 140psi before I got scared, because the tank appears to be 50+ years old. Probably perfectly fine at that pressure, but I didn’t see any psi cut off, so I just shut it off.

Held that 140 psi for at least an hour, which is when I emptied it.

I had to move it from where it was to remodel, so it is now in a garage. Appears to have been always kept under cover. And it weighs a couple hundred lbs.

So, what say you?

Is it a Sears unit? Built this way? Mish-mash of parts over the years? Value?

And BTW, I was a member here for many, many years, but the ”new look” website wouldn’t take my old info, so had to rejoin.
