Quincy Air Compressor Help needed

I agree with Mopar Head, I love old stuff and refurbish it. I have a Westinghouse that I found in the early 80's still works perfect but did have to tune up the reed valves . Working on a disc/belt sander from the 50's made by Atlas Press in Mich. the castings & machine work are something you can't buy today ! I love keeping old stuff working
