Remington-Hayburn Rifle
Re: Remington-Hayburn Rifle
If your rifle is the Argentine Model it is the No 1 Model Rolling Block. The Hepburn was an entirely different action. Your rifle was originally chambered for the 11mm Spanish (.43 Spanish) cartridge. The black powder No 1 rifles were not serial numbered. If you remove the butt stock you will find #'s on the left sides of both tangs but these were assembly #'s only. These rifles were frequently refinished either by the importer or the Argentines. Originally, the receiver of the rifle would be color case hardened. If refinished, it would be blued but may take on a very mottled appearance. They are generally in very nice condition with near perfect bores. They make great shooters. All components for reloading are readily available. But remember, this is a black powder action so keep loads mild.
