A piece behind the coin slot inside has a few welds (see photos). Has what looks like the original lock mechanism, the keys look newer.

I am not an expert on slot machines, so this will be sold as-is. When a dime is inserted, the coin wheel turns slowly, and drops the coin, but that's about it. He told me his father had spent $800 to have it repaired years ago, and that's what I have set the current reserve at. He remembers it working, but it has been sitting for quite a while, and now the reels don't operate.
