Manufactured form 1868 to 1888. This is an excellent example of a very desirable Remington Rolling Block No. 1 Sporting Rifle with a half octagon barrel that is numbered to the gun (serial number marked on the bottom flat under the forearm). The top barrel flat is marked "E. REMINGTON & SONS. ILION. N.Y." ahead of the rear sight. The rifle is equipped with a German silver blade front sight and a folding adjustable rear peep sight. The underside of the barrel has the caliber marking of "40 70." (for 40-70 Sharps caliber) The receiver has the octagon top and is marked with the six-line patent information on the left side. The forend tip, buttplate, receiver and trigger guard are casehardened and the remaining metal surfaces are blue. Mounted with a nicely figured smooth walnut forearm and straight grip stock. The forend has a Remington iron tip. Remington's production of the rolling block firearm in one form or another lasted from 1867 to 1934. The No. 1 action was the largest of the rolling blocks, chambered for the smallest to the largest calibers of the period. Comes with an original box of UMC 40-70 ammunition (20/20).
