Bell and Howell Projector

This is a Bell and Howell Filmo Showmaster Projector 129 H. It's in almost mint condition. The metal cables that turn the wheel are a little gapped in a couple spots, but it fully operates, and comes in a case that is in excellent condition.

I've been looking all over the internet and can only find a few values at which are current listing prices, and not sold. I'd like to see what value everyone would put on this beautiful piece of film history.
