I acquired a 12 ga LC Smith hammer gun from my grandfather. Using your information, I believe it was made in 1909. Serial number is 161058. It has an F stamped under the receiver's serial number. It has an O preceding the serial number on the forearm. It has damascus barrels. I need two parts. The left hammer # 15 and a firing pin. Are these parts available? I called Numrich and they said "out of stock" but might get them in sometime. I would appreciate any help.
