Only an estimated 18,000 New Model Police revolvers were manufactured total between 1865 and 1873 in percussion and then many were converted for metallic cartridges thereafter. This exceptional example remains in original percussion form and has the desirable 6 1/2 inch barrel length and a pair of smooth rosewood grips. The shorter barrel lengths were far more common than the longer barrel lengths. 6 1/2 inch barrels were the longest offered and are the scarcest. The few that are known in this barrel length in original percussion form are generally well used unlike this example. The barrel is numbered "663" on the bottom, and the frame and grips are marked "3866." It has a German silver half moon front sight and the standard frame groove rear sight. It has a blue finish on the major components, a nitre blue finish on the screws, and a silver plated finish on the brass trigger guard.
