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 "13407" marked on the front surface of the frame below the loading lever, underside of the barrel, inside of the hammer well (partially visible), 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 boxed script "ABB" (A.B. Blackington) and "CSL" (Charles S. Lowell) inspection cartouches stamped on both sides of the grip at the bottom.

Fine, retains 60% original blue finish with scattered patches of flaking and smooth brown and gray patina on the balance, 70% vivid original case colors on the loading lever and hammer with the trigger turned to a smooth gray, and sharp markings and edges in the metal overall. Grip is also fine with defined edges, some scattered light handling marks and nicks, and crisp cartouches. Mechanically excellent.
