As luck would have it a Model 21 comes my way and I have just loaned my book to a friend. So I'll ask you gentlemen for help. This is serial # 30521. It is a 20ga.,vent rib gun with 3" chambers and ejectors. It has 28" barrels choked FULL/FULL. About how many of these were produced? I can have a better pic posted today but I tried to show the barrel stamping. Paul
