While in my daily travels around the San Francisco peninsula for my work, I stumbled upon what I believe is an oil pump pictured below. Not sure if it is complete or not. I couldn't find any markings on it. The shop owner might be interested in selling it, although he wasn't available at the time when I was at his body shop. I'll try him later. However, before I do, I'd like to know the circa of this pump, what kind/brand is it and any approximate value? I'd like to make him an offer. It's very heavy and still bolted down to the cement floor.

Thanks.
