I have a 20 inch barrel saddlering with no serial number in cal,50-70.The tang is marked with three lines starting with Remington's and third line begins with Dec 31,1872 with the rest unreadable. Barrel is round with a witness mark and the letter FB. The sight is a carbine leaf with 3,5 and 7 markings. The barrelband has a U marked on it. The right side of the forearm has a FCW in script stamp.The bore is in excellent shape and the firearm seems well preserved. The action has a half cock, but the hammer does not fall to halfcock upon the closing of the breech.
Any information would be appreciated.
