Very fine as arsenal refurbished and subsequently restored to World War II configuration, retaining 85% plus arsenal parkerized finish with light cycling wear, some dried grease, scattered minor patches of spotting/oxidation, some brown patina, some minor edge wear, and minor handling marks. The stock is very good as sanded and re-oiled with numerous scattered minor handling marks. Mechanically excellent. This is a rare opportunity to add the most elusive of all M1 Carbine manufacturers to your collection!
