My last one was from an want ad. He had two early Bally/Sterns that haven't been used in 25 years which were found in a basement of a house that was going to be gutted. I made a deal with the guy to restore one to a players condition game one and I'll take the other one as payment. Was able to do it with parts on hand and a lot of labor.
I love finding them this way ..
