Help to ID old air compressor pump

[1970rs]

Can anyone help me ID this compressor pump. It is a 2 stage and had a 8hp motor powering it. Someone has removed or painted over the tag at some point. Trying to determine the size of it. Thanks for any help anyone can provide. It also has GT5 cast into the base of the pump.

This was originally sold as a Dayton compressor. I'm not sure who actually made them for Grainger.

I will search also, but any idea on how to identify pressure and CFM of it?

It's 2 stage so usually 175 PSI max and I'm going to guess 3 - 5 HP.

Thanks everyone for your help. It was ran with a 8hp motor which is most likely more than it needed. Im guessing its 15-18 CFM @ 100PSI
