Old compressor identification

[Aaron2]

Hi All,
I'd like to use the experience pool here to help ID a compressor. It is for sale near me, but the guy selling it says there are no tags. Just based on shape I wager its a Saylor Beall 705 but the unloader looks different. Anyone have any ideas?

This is a Chinese SB clone. The tank is ancient. The motor looks like a huge old Tamper which will probably run forever.

Thanks MacMcMac. I had read on here that the SB is cloned a lot so not too surprising.
