OK, I had a good look at it today. It's a Gomco 792 aspirator. It does use
oil after all. I found a box packed with it, with some spares, and a new can
of vacuum oil! The parts kit includes a new filter. There is also a manual,
that is little more than a brochure. Several of these pumps are currently
advertised on the net for around $400.00, so I guess a tool gloat is in
order! The pump is apparently a rotary vane type made of cast iron with
bronze slides/vanes.

My mistake, it's a Gomco 789. Spare parts no longer available. Otherwise it
works well. It's still worth much more than I paid for it. The pump will be
just dandy for my needs. Any kind of used vacuum pump is very hard to find
where I live. There are lot's of research labs in the Greater Victoria area,
but used pumps just seem to be stored away, and seldom wind up on the local
market.
