Very fine as arsenal refurbished and subsequently built back to World War II configuration, retaining most of the finish with some minor cycling wear, thinning and brown patina visible on the bolt, some dried grease, and some light handling marks. The stock is fine as sanded and re-oiled with some minor visible compression marks. Mechanically excellent.
