Most of the U.S. contract New Model Army revolvers were manufactured in 1863-1865, but this model remained in production until 1875. They were the second most widely issued revolvers of the Civil War after only Colt's Model 1860 Army, and continued to be used during the settlement of the West and the late 19th century 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 and grip frame. The grips are numbered to another gun.

Very good with 30% original blue finish, traces of original case colors on the hammer, gray and brown patina on the balance, distinct cylinder drag lines, and minor scratches and nicks. The period replacement grips are good with moderate handling wear, slight chips at the toe, and general light scrapes and dings. Mechanically fine.
