Yeah, I am saying there was some manufacturer that made guns for such purpose. Now, I do NOT think it was stamped "Bank Guard Gun", but I do know that at BOTH booths I stopped at that had the same gun they BOTH said the purpose of the gun was "as made by the manufacurer" was for banks and wells fargo guards... BOTH said the same thing... And BEFORE they told me anything when I saw the GUNS I said--"Wow, this looks exactly like the guns I saw the bank guards carry when I was a kid in the 1960's".... Both gun guys said they thought the guns were used from the 40's to the 60's. Single barrel 12 gauge, funny way of opening the barrel, very short barrel, very dark almost black finish.
