Tool's very first vacuum pump Answered

My boss cleaned out his office since he's retiring (and I'll miss him, as long as you did your job he left you alone, maybe quarterly reports, just the kind of boss I need) anyways he gave me a vacuum pump, he said its been there unused as long as he has >35years. So I thought I'd get advice before i even plug it in. It's a Curtin Matheson Scientific googleing gave me no info other than the Gast AD220 oil it requires can be substituted with sae 10 detergent oil. Anyone familiar? any advice?
