My Brazilian has a 1917 surplus (?) rounded frame, and the SN is 163,591; features that do not fit the usual configuration. The frame, cylinder, extractor and (I believe) barrel match, although some ape stamped the importer's mark over the number. The inspector's mark is S34. The S&W DA 45 is on the left side of the barrel. The cylinder has a very faint plum color, but I see no sign of refinish, as both the small S&W and the Brazilian crest are sharp with raised features. Overall, the finish is VG plus per Supica. The lanyard ring is present. The stocks do not match, having a stamped SN of 167,906. I would appreciate suggestions that would resolve these inconsistencies to my mind. Thanks....
