Cosmetically it is an 1899 C with an 1895 Serial number. Something is not adding up. What is the serial number under the buttplate and does it have the JM mark on the barrel under the forearm? I know you could get the bolt replaced on 1895's to an 1899 bolt back in the day but the shell counter hole on the side adds to the mystery.
I do not mean to flame your sale but it begs the question if you have ever gotten a letter for it?
