You might already know this but the tag in the second pic has the pressure ratings info for the tank and but does say the tank was built on 1991, so the compressor was likely built around that time. I take it the compressor is for sale and you're trying to track down stats like CFM and PSI?
Actually, i am looking for the model or serial number so I can look for a manual to see how original it is? I have never seen a 2 stage 40 gallon before.
Note: I already bought it. I cleaned it up, spray painted it and re-plumbed it. Still working on changing all the switches so they will light up when in use or has an error.
I also tested it today with an air blow gun (tip removed) with a hose into a quick connect to 1/4" ****** into 1/2" main line. Results - the 2 stage kicked on at 90 psi and fully charged with the air blow gun lever fully depressed.

Originally I was looking for a 60 gallon too. However, after I seen this 2 stage work on a 1/4" hose full discharge. I was impressed. It might not keep up with a full discharge if a 1/2" hose but I do not have anything that big.
This was also a CL find for $300 (could have probably got it for $250 but I can't find any 2 stages for less that $500 used). I spent another approx $60 to repaint, re-plumb, re-wire and add little a hook to suit my needs. I am still waiting for a power switch, that is why the panel is off. I want the switches to light up again when in use. I just have not figure out how the oil light works. Also the indicator lights are 28 volts which is very unique to military.
Anyways, here is the final outcome. Hope you guys like it !!

I forgot to mention, changed the oil, air filter and at least a gallon of water came out of the thing when I got it home. I let the compressor sit for 2 days without the drain plug to dry it out. When I had the side plug off during re-plumbing, I sprayed WD 40 in it to help push some of the condensation out.

Looks like a Schulz pump to me. I believe Champion uses the same pump on some of their cheaper units. Decent pump.
I think you are correct, Thank You! It looks nearly just like this one...right down to the way the intercooler is routed, main piston is larger than the second one (some needs to explain to me how compression works on this). The main block casing is a little different but the workmanship design look very much like a Schulz pump.
