it is a single phase dual voltage motor with 20/10 HP.
Model number 33-518
type 33-1019
Under the sawdust, greasy, oily coating, it almost looks like new.
The tank had a lot of water in it, which is concerning.
Where would I look to find someone to test the tank?
I'll have my electrician look at it on Monday.
If the tank checks out and motors good, I'll start looking into a rebuild
of the pump.
Should be a fun project!

I've got a similiar unit, can you take pics of ll the plumbing from head to the tank?

Clean it, change the oil and fire it up. If it is not making any knock sounds don't waste you time and money on a rebuild.
The compressor was abandoned in an old 1920's building.
Who owned it, and what it was used for I don't know.

Ideally you should have it professionally inspected and hydrotested regardless of what anyone may suggest for do-it-yourself testing. Look for "hydrostatic testing services" in the yellow pages, ThomasNet.com or Google.
