An estimated 23,000 of these revolvers were manufactured in the late 1850s and early 1860s, and most were purchased by the U.S. Government. This example has the standard "STARR. ARMS. CO. NEW. YORK." address on left side of frame and "STARR'S PATENT JAN. 15, 1856" on the right. The serial numbers match on the front of the barrel lug, receiver, cylinder, in the hammer well, and front of the hammer. There are small inspection marks on some components. The revolver is fitted with a smooth one piece walnut grip with a cartouche on each side. "ABB" (A.B. Blackington 1860-1862) is on the left side, and "CSL" ( Major Charles S. Lowell 1858-1861) is on the right. The matching serial number is marked on several components, and an intertwined "JG" is stamped on the front of the frame at the hinge.
