Rogers & Spencer of Utica, New York manufactured an estimated 5,800 of these revolvers in 1865. The Rogers & Spencer Co., was awarded a contract by the Ordnance Department for 5,000 .44 caliber revolvers in November, 1864. When the Civil War ended in April, 1865, 1,500 revolvers had been delivered; the remaining 3,500 were delivered by September 1865. The revolvers were apparently never issued and were subsequently sold by military surplus dealer Francis Bannerman. Matching serial number "4359" marked on the barrel, loading lever, cylinder, frame, butt and underside of both grip panels. Various components have "B" inspection marks. Boxed script "RPB" inspection cartouche stamped on the left grip panel.

Very fine, retains 75% plus original blue finish with scattered light flaking, mostly concentrated on the cylinder, smooth brown patina on the balance, and sharp markings and edges in the metal overall. Grips are also very fine with some minor nicks and a few chips visible along the otherwise defined bottom edges, some light handling marks, and an exceptionally crisp cartouche. Mechanically excellent.
