I went by my favorite pawn shop at lunch the other day and found a 20 inch 1897 riot gun in 12 ga. it is original and is in great shape. The bore was dusty but cleaned up and is miror like now. It shows to be manufactured in 1903. Also it is stamped "Committee Public Safety" on the left side of the receiver. Have not had much luck finding any information on the history of the markings. I have owned other 1897's but this one is cleaner and tighter than any I have found. I walked out with it in hand for $300.00. It will be passed on when I am passed on. Thanks for any information.
