SN: 18570. Made in 1936. 7.62x38R with a 4.5"" barrel. Bore has moderate frosting with strong rifling present. Very rare Polish variant of the Nagant revolver with matching numbers and dated 1936 making this one of the very last produced examples. Revolver retains 35% of factory blue with scattered brown patina and shallow pitting peppered around frame. Grips show expected handling wear with dull checkering remaining. Action functions properly. Overall good condition example of an exceptionally rare revolver.
