Smith & Wesson model 1 2nd issue serial is 117xxx. Has 3 patent dates on the cylinder. Have not tried to fire it. Someone did a number on the rod under the barrel with a pliers and also did a number on grip screw. Top screw is missing on sight as seen in pictures. Everything seems to function. Unsure if box is original or not stickers definitely are not. Open to discussion can provide more pictures. Not real familiar with these older guns
