So, some years back I received an (at the time) unknown rusty firearm that had been stuck up in a basement ceiling. It got put on a shelf in my back room until this past weekend. I managed to scrub off some of the rust with some steel wool, and found both the maker and SN, but not a caliber mark. I've got a request in to the Center Of The West museum for info on the gun, because it's apparently too old for Savage to still have the records of. My question is, would it be worth it to have it restored, and if so, what would something like that cost?
