Some of you may be familiar with the name David Guest, he has around 500 16mm features which he inherited from his father. He is currently advertising two Debrie projectors on Ebay, untested, but known to be working when last used 5 years ago. As he is an experienced cine man, wouldn't you think the obvious thing to do is plug them in and see if they run, and maybe run a short (400ft) film through them, rather than letting someone buy something not knowing if it works or not.
