Question Keystone Air Compressor

I have just acquired an old Keystone air compressor of mid-50s vintage. The pump is a two-stage, horizontally opposed, cast-iron unit. My question is anybody on this forum familiar with Keystone compressors? Is the company still in business? Do you know where I can get a manual for the compressor. I have the serial number and the model number.

Welcome to the forums.

The first step is posting the model number although in reading around there is very little tech info available. It looks like the company is still active but no real mention of them in searches.
