The single barrel Bank Guard 12 gauges I saw broke in the basic same way as the standard ones do, but the receiver---if I recall correctly---had a ring on one side and the overall shape was slightly more rounded than a typical and yes there was something about the actual pivot that struck me as not common. I wish I could be more specific but I need to see one or a picture of one again.

And as I said, BOTH gun dealers said these guns were made from the manufacturer for Guards. So anyone who has one or knows the story will know exactly the gun I am trying to find. I only wish now that I had bought the one that was in good condition. It was around $300. Ever have one of these gun quests just drive ya crazy??!!!
