This variation started about #11672 and this one is SN 11991 and is matching. The mechanical function is very good, crisp and tight and has a good bore with strong rifling that is a little dark with some corrosion. The barrel to hinge is tight and the grips are not cracked but were lightly sanded. The frame has 55% silver and the barrel retains 18% faded blue. There are far less of this variation than that of the 2nd quality revolver with 4402 units sold at a discount.
