The serial # is 919353. So I'm thinking the year could be 91 because of the magazine. There was a small paragraph on the gun in the magazine, and said it has a 1 in 66 twist, which I don't know what that means? Most other guns in there were 1 in 32, or 1 in 48. There wasn't any flint in the box either. I'm sure I'll have loads of questions until I become fully accustomed to this new style of shooting and hunting.
