Interesting thread. I was given a M12, 32", no rib, FC from a fellow whose father was the comptroller for Wichester in CT. When he left the company in 1952, they gave him the gun as aparting gift and factory engraved his initials on the trigger guard. The stock has some scratches on it from moving it from house to house for the last 50+ years, but, it's never been fired. Wish he still had the box and any papers that went with it!!
