No label anybody recognize this pump

I picked this pump up but there is no label on it. Does anybody recognize it?

Looks like a DeLaval #78 pump. Hook it up with a oil reclaimer and they make a good pump.

How much vacuum can I get with it? I got a honda 11 hp gas motor with it. Also is the bearing ends on this pump supposed to be oiled? It has plugs in the bearing ends and has two ports on the inlet of the pump.
