Manufactured in 1875, this is one of approximately 7,500 manufactured known as the "cloverleaf" variation, due to the shape of their four-shot cylinder. It has standard markings and features as well as British proofs on the bottom of the barrel and the cylinder. Matching serial numbers are on the bottom of the barrel, butt, and inside of both grips. The right side of the frame is marked "10A/42" in white lacquer. Includes a rarely seen "pipe" case fitted for the revolver.
