Good question. I have a promotional ad by Quincy from that time, it
asks "Is there compressed air on Mars? QUINCY COMPRESSOR, FIT INTO
YOUR FUTURE". It hangs on the wall behind the compressor.

Note also that, though the compressor is that old, I installed a new
single phase motor on it.

Dunno bout Quincys or Mars, but my Gardner Denver looks to be older
than me. I started out running it with two 1/4 HP motors belted
together, then an older 1/2 that needed the re-set poked about every
third start. now I have it on a 50Hz. half that seems to work OK and
drives the compressor at 535 RPM (Max. 600). I have a 3/4 in reserve
if I ever need it. I never realized how much I needed air until I got
it!
