Can anyone tell me what this unknown 7mm Remington Single Shot rifle is? The data on the Rifle says, Remington Arms-Union Metallic CTG. CO. Rem Works, Ilion, NY, U.S.A. PATD. OCT.22.1901 On the barrel it says, "Cal. 7MM" It's been in my family for years and the barrel is completely obscured. Is it worth it to try to get it back in Firing Condition? The stock has a few scuffs but the action is smooth and the trigger pull is smooth as butter. I am wondering if it may be made with Damascus Steel and whether or not it could fire standard 7MM cartridges? I know that it is newer than 1901, but I cannot find any serial number on the rifle...? Strange if you ask me.
