I believe this is a Japanese auto 5 forearm. It is in excellent shape with a couple minor scuffs and some tape adhesive ect on it. I took the original forearm off my 1958 A-5 standard 12 gauge to see if it would fit and it mostly did but would require fitting where it meets the receiver. It appears to have never been fit to a gun as I don’t see any wood removed. $10 shipping. I would consider offers and like to barter. Always interested in Remington model 11 / A-5 barrels and synthetic A-5 stocks.
