These rifles were manufactured from c. 1883 until 1907, but the low serial number and "E. REMINGTON & SONS. ILION. N.Y." address on the barrel indicates this rifle was manufactured c. 1883-1888 before the company was reorganized as Remington Arms Co. The barrel is equipped with a Beach style combination front sight with globe and blade, and a notch and peep ladder rear sight. The caliber designation "40 1 7/8" (.40-45 Rem/.40-50 Sharps Straight) is marked on the bottom of the barrel ahead of the forearm. "HEPBURNS PAT./OCT. 7TH 1879." marked on the right of the frame. Matching serial number "138" marked on the underside of the barrel, rear surface of the forearm, and lower tang. Mounted with a smooth walnut forearm with casehardened forend cap and round knob checkered pistol grip stock, nicely figured buttstock, and casehardened buttplate.
