The Starr Model 1858 and Model 1863 revolvers as a group were the third most widely used revolvers by the Union forces during the Civil War. Approximately 23,000 Model 1858 Army revolvers were manufactured in the late 1850s to early 1860s, with 21,000 reportedly sold to the U.S. government. The frame has the New York address on the left side and the 1856 patent date on the right. Most of the components have single letter inspection marks. All matching visible serial numbers marked on the front surface of the frame below the loading lever, underside of the barrel, inside of the hammer well, hammer, cylinder, left side of the front grip strap, underside of the rear grip strap, and stamped on the top surface of the one-piece walnut grip. Crisp bordered script "BH" inspection cartouches stamped on both sides of the grip at the bottom.

Very fine, retains 70% plus bright original high polish blue finish with the straps and trigger guard turned to a smooth gray patina, scattered patches of flaking showing a mix of smooth brown and gray patinas, 75% vivid original case colors on the loading lever and hammer with the trigger turned to a smooth gray patina, and sharp markings and edges in the metal overall. Grip is also very fine with defined edges, a few minor handling marks, and exceptionally crisp cartouches. Mechanically excellent.
