Most of the U.S. inspected New Model Army revolvers were manufactured in 1863-1865, but the model remained in production until 1875. They were the second most widely issued revolvers of the Civil War after Colt's Model 1860 Army, and continued to be used in the West during the settlement of the West and the post-Civil War Indian Wars. It has standard markings and features, small inspection markings, a "GP" cartouche on the left grip, and matching serial numbers on the barrel, rear face of the cylinder, grip frame, and grips.

Very good with 40% original blue finish, smooth brown and gray patina where the finish has flaked, vibrant original case colors on the right side of the hammer, subtler case colors on the left side hammer, aged patina on the trigger guard, light edge wear, and minor oxidation. The grips are fair with numerous surface chips, gouges, dents, and scratches from use. Mechanically excellent.
