Got this as a curb find a few days ago, not a ton left of it but figured there'd be some decent parts left. Trying to figure out what it was... Pretty sure it was a bingo, but beyond that I don't know yet. I can't find any conclusive identifying marks on the thing. Looks like it has an automatic ball feed mechanism. Shooter rod has a 'beehive' housing. Two buttons on the front are red and green recessed marbled plastic type. There's a tag in the bottom that reads "No. 6550".
