Here's a Garwin vacuum pump, and a Beryl D'Shannon air/oil separator that came with my 150J project.
The pump spins freely, but has been sitting on a shelf for 18 years, so probably could use a rebuild kit.
The air/oil separator has no moving parts... it could use a fresh coat of paint though.

$200 includes shipping to continental US.
I think this is my last "for sale" ad for a while (thank goodness)! Have a great day!
