Welcome! I've read your blog many times! Lots of good stuff. Shop Goodwill does have derelict machines. I've been learning sssssooooooooo much lately. It is my opinion that people know they don't work so they don't bother selling them at yard sales - so they get donated... Shop Goodwill knows you can't look them over so they get top dollar. Lately the ones I've gotten have had all kinds of issues. I'll post on the vintage shop later about the one I'm stumped with.
