Serial #4787, 32 rim fire, 3 1/2 inch barrel, very good five groove bore with areas of erosion. These revolvers were built from 1865 to 1873 in percussion with the option of 32 rim fire or a combination of both available after 1873. This one remains in fine condition with 40% blue on the barrel, 70% nickel on the trigger guard, and traces of finish on the frame and cylinder. The wood grips look great and fit perfectly, they show light wear. The left side of the grip frame, the trigger guard, barrel bottom and inside both grips are marked 4787. The cylinder and recoil shield are stamped 537. Gun works well. The revolver comes in a brown leather holster, close inspection reveals an oval and "son" marking indicating that it is a Iver Johnson holster that is 50 years newer than the gun. This was cutting edge police technology 150 years ago, comparable to a new SIG or Glock today. This is listed in Flayderman's as 5E-029. Free shipping.
