Help identifying this compressor

[twowheelhabit]

Looking for any information on this compressor. It is on a Brunner but I am not sure if this 3 cylinder compressor is the original
Thanks in advance

Maybe a Champion?

Guessing the pump isn't original. An image search of Brunner A-330 isn't that pump.

To me, that bolt-on crankshaft bearing cap pegs it as a Champion - I think they are still using that exact same part, see this modern-day pump as a reference (the crankcase can handle 3 cylinders - also see location of oil fill boss and sight glass):
