Remington produced approximately 7000 Model 1861 Navy revolvers (a.k.a. Old Model Navy) in 1862. The top barrel flat is marked "PATENTED DEC. 17, 1861 / MANUFACTURED BY REMINGTON ILION, N.Y.". It has the six-shot round cylinder, 7 3/8 inch octagon barrel, German silver cone front sight with grooved top strap rear sight, brass trigger guard, and walnut grips. This revolver has the early production frame with the barrel threads concealed at the breech. Small "W" inspector marks are present on the left side of the barrel and frame, with an additional "W" on the cylinder. Matching serial number on barrel and frame. The left grip panel is stamped with a script boxed "CGC" cartouche. This is the same inspector as on the martially inspected Henry lever action rifles!
