Hi Marc...

25 torr is pretty low as far as a diecent vacuum goes...
the systems sound like they might be the rotory vane type

there is the oil diffusion type but they can go as low as "milli torr"

I'll bet if you put one on Ebay it will sell for nearly 100$


I'd keep at least 2 for myself if I had several in my posession ;)
