Colt 2nd Model Richards Conversion. Referred to as the Transition Model Type II Richards, found in serial number range 190000 to 199000. The most visible difference between the type one is that the hammer cuts through the recoil shield and directly strikes the back of the cartridge, therefore there is no rear sight on the recoil shield. This example has all matching numbers on frame, barrel, trigger guard, back strap, loading gate and cylinder. Wedge is not numbered. Three screw frame is not cut for shoulder stock. Two line patent address and single line barrel address. The cylinder is rebated and roll engraved with a near perfect Naval battle scent. The hammer, gate and conversion ring on a Second Model is the Richards Mason type. This revolver is in full factory nickel plate with the exception of the case colored hammer, built with the brass trigger guard and steel frame. CONDITION: Overall gun retains 80% original factory with usual handling marks. 75-80% nickel on trigger guard, starting to flake. Case colors have dulled on hammer. Walnut grips are slightly shy to metal. Indexes and locks up like new. Strong, defined rifling with a frosty bore. A great example of a late Transition Model Conversion.
