K stamp on receiver top. "K" letter date code (1934) marked on the chamber, "S/42" code marked front toggle, "B/90", "S/91" and "drooped eagle" inspected extension.

Very good as partially refinished (cold blue touch up on left side of frame), with areas of brown and gray patina, edge wear, spotting and handing marks. The grips are very good, with dings and flat spots. Mechanically excellent.
