Bacon Manufacture Co. Derringer .32 Rimfire caliber antique handgun. This is a rare brass frame variation with an open breech that dovetails at the top to meet the barrel. Barrel address has very tiny letters and is stamped so that only half of the address is visible. Note this address has not been buffed or altered in anyway. Barrel has a blue brown finish that is more blue than brown. Barrel is 3 7/8"" long and overall length 6 1/2"". Gun works perfectly and has no looseness. Grips are very good with no cracks. Very scarce variation described on page 468 of Flaydermans Guide to Antique American Firearms.
