Very nice original Big Bang 8FR cannon. The R denotes " noise regulation". These were produced from 1924 to 1935. 100% complete. The cannon is in very good shape. I have not tried this out but if you are to use this I would suggest getting a new plunger so you don't break the old one. They are rather scarce to find now. The plunger is an original old one. The wood ammo chest stopper is a modern replacement.*** U.S. SHIPPING ONLY ***. PLEASE DO NOT PAY UNTIL INVOICED BY ME. PAYMENT DUE WITHIN 48 HOURS OF INVOICE.
