Ok, this much I know. The compressor is a Paasche model D. 1/4 hp electric motor that runs on household 110vac. It delivers 1/2cfm at 20psi pressure and can produce 40psi at lower volume.

This compressor is as simple as a brick, and weighs in at around 20 pounds.

If there is any interest, let me know and I will get pictures and listen to offers on price. Otherwise it goes eBay.
