Colt 1849 Pocket .31 caliber with Crowned Muzzle. One of the rarest variations. There is 95% of the blue on the barrel. All of the case colors are present, but have turned dark. Grips are excellent. This was the last evolutionary change made in the Colt 1849 series. Approximately 400 of these were made, but it is estimated that less than 50 survived.
