That is a Frigidaire "Standard Line" from 1935. It uses F-114 which works at roughly a quarter of the pressure of F-12, but it's still a Freon type. High side metering is by capillary tube. Freon was developed by Thomas Midgley, an employee of General Motors, so Frigidaire was the first to use it. This book has info on this model starting on p43 babel.hathitrust.org/cgi/pt?id=wu.89089680359;view=1up;seq=55It looks like the fridge has been stored somewhere exposed to the outside given the surface rust, but should respond well to cosmetic restoration. The compressor should be ok. Replacing the compressor in this fridge would really mean converting the whole thing to work on another refrigerant; R134a probably being the easiest. The problem is that no domestic modern fridge works under the same conditions

I have a 37 like this Travis gave me. Cablehack is right they are R-114 units. The low side will be in a vacuum when running. R-114 was not widely used so finding some nowadays might be hard. It may still be fully charged, mine is. If so I would not try to do any conversion to something else. You would have to replace cap tube and compressor at the least to make another refrigerant work.
I have a test cord with a switch on the start winding that I can use to hook directly to a compressor and run it to see if it works and if the system is still full. Should have something for an overload in the circuit also. You could also try a 3 in 1 start relay hooked directly to the compressor to bypass all the old wiring and see if it works.

Thank you very much, both of you! I'll pass this onto my friend and keep everyone updated.
