Carla, this is a good example:

This compressor sold for $125. This looks like a 5 HP 3 phase Champion
or DeVilbiss compressor with air filter and regulator attached. The ad
says "Cochrane compressor", but Cochrane is a compressor dealer in
Chicagoland. (my favorite, too).

Note a big oil residue on the tank. Either the pump leaks, or the oil was
drained carelessly at some point. The right side of the oil outline
suggests the latter.

This is a oil lubricated model,two stage pump.

I personally think that this compressor should have sold for $50.
