Well, I picked up that old Quincy 325 compressor on an 80gal horizontal tank and a 7.5hp 1ph 220v motor. The thing has good oil pressure, builds pressure fast, and runs nice and smooth. I think for $200 I got a heck of a deal on it. The thing was a lot bigger than I thought it was going to be. I had to take the pump and motor off of the tank just to get it all in the truck. I bet the pump alone weights 250lbs…probably 100lbs for the motor, and another 200lbs+ for the tank. It’s a beast.
Based off of the numbers on the compressor, it’s from the 60’s. So that means that the tank probably is too. I’m assuming I’ll need to pressure test the tank before I use it………but even if it tests good, how safe is a compressor tank that is over 50 years old? I’m assuming these things were built like tanks….but if safety in a concern, I’ll just find a never used thank and scrap out the old one.
What do you guys think?
By the way…here is what the compressor will look like once I get it all cleaned up and painted….right now it’s pretty nasty looking. If I remember right…it should put out around 24 cfh at 175psi……I don’t think I’ll ever need more air than that.

At first I thought the picture was of your compressor. I was like DAMN $200 for that, then read where that is just an inspirational pic. Lets see some real pics. The 325 is a time proven workhorse. Expect about 15cfm @ 175psi or ~20cfm @ 90psi max, depending on HP--> RPM. A 7.5hp single phase motor is really nice, but a bit overkill for that pump. You may want to check the RPM to make sure it is not over speeding. Yea they are not lite, ~250lbs sounds right for the pump. I'd probably start with a good tune up, check valves, and change the oil. 
Also where are you getting a weight of 295lbs for a 325? My catalog shows 260lbs ship wt.
