I have come into possession of a Remington Hepburn #3 . I believe it to be a Grade B Match Rifle , I'm looking for someone with knowledge of these rifles . The s/n is 58xx . It has the E. Remington and sons roll stamp on the barrel , so I know from research that it was made prior to 1888 . I also have questions about the Gunsmith who rebuilt the rifle at some point long ago in it history . His name was C.C Johnson , of Thackery , Ohio . Mr. Johnson somehow took a barrel chambered for an old BP round (38 . 1 3/4) , and made it a .22 Hornet ! Which only presents more questions . Any information on either subject would be appreciated ! I will post some Pics , if anyone might have some info .
