This is one of the approximately 5,800 percussion revolvers manufactured circa 1863-65 by Rogers & Spencer of Willowdale, New York. The U.S. Ordnance contract was for 5,000 revolvers. There is no record of issuance of any of these revolvers due to their delivery in the very last month of the Civil War. The top of the frame is marked "ROGERS & SPENCER/UTICA NY". The matching serial numbers are found on the barrel, loading lever, frame, cylinder, and butt. There are small single letter "B" inspection marks on most of the parts including the bottom of each grip panel. Finished blue with casehardened hammer, trigger and loading lever assembly and fitted with smooth walnut grips with a sharp "RPB" cartouche on the lower left panel.
