Older Quincy Air Compressor Info needed

I recently acquired an older Quincy air compressor, the tag reads "A4 7 210058 Size 2 1/2 X 2 1/2." I called my local Quincy dealer, who unfortunately is not very local & mainly deals with commercial accounts. All they were able to tell me was that the pump was obsolete.

What I am trying to find out is:
1. General specifications, including correct rpm range.
2. Parts diagram
3. Availability and price of service parts (gaskets, rings,valves, in that order)
4. Diagram/explanation of the separate unloader assembly that seems unique to Quincy compressors. Parts list also.
5. Some idea of what size motor this unit needs. It had a large, old looking motor that did not work when I got it. I suspect a real 1-1/2 or 2 hp 1725 rpm motor would be okay, but would like confirmation/correction.

Any advice/help is appreciated.

From Quincy catalog No. 6600-1. The A4 is a single cylinder.

1/2 hp yields 1.56 cfm @ 100 psi @ 400 RPM.
3/4 hp yields 2.46 cfm @ 100 psi @ 630 RPM.
approximate shipping wt is 65 lbs.

Note; compressors are rated at "free air" which means output has been compressed, then let down to atmospheric for volume measurement. You will not get the cfm at the compressed state.

I looked there but did not find anything useful except the name of my local distributer.

Go back to that site and see if they have a customer service email. I had an identical situation with a curtis compressor. Emailed them and got a response telling what rpm, motor size and rated cfm.
