Like any older double you need to go over the gun. With that being said we know that factory 3" Long range guns where made and not stamped For whatever reason. A gun is what it is and why Would / or why should you pass on a great LRWF 3"Gun just because its not marked. Again if you go over It and all is correct jump on it and enjoy and drop waterfowl @ 60 yards with ease. Toss some Bismuth 1-5/8 x 3"x 2,3,4 or 5 And you will be surprised how far these gun toss tight Patterns that will drop waterfowl/game.
