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, only 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. Full octagon barrel with nickel-silver cone front sight and a sighting groove on the top strap. Six-shot cylinder with safety notches between the chambers. The revolver barrel, frame, cylinder, trigger guard and back strap have a high polish blue finish, and the loading lever, hammer, and trigger have a dark casehardened finish. The top strap is roll-stamped "RODGERS & SPENCER/ UTICA, N.Y.". The matching serial number is stamped on the underside of the barrel, loading lever, cylinder, and bottom of the back strap. Small Ordnance "B" sub-inspection marks are stamped on most components. The lower left grip is stamped with a crisp "RPB" cartouche.
