my friends got a Winchester Model 1887 lever action shotgun. it's missing the hammer and some other parts and is in rough shape but looks cool as hell. I was tinking about buying it from him for a wall hanger. The problem is either it was ordered with a 17" barrel or someone cut the barrel down years ago. would a shotgun this old with a 17" barrel be considered a class 3 item? would it be illegal even though it's not capable of fireing.
