I recently got a 1903 Springfield. Serial number puts it as a later 1918 gun. Barrel is marked 1-19. Stock cartouche is marked RLB. Which from my search says this is correct for the serial number range. The bore is very good. Is it possible that this is an original gun, not a refurbished gun. It is is overall great shape for its age. Any help would be appreciated as I know very little about these. Thanks
