I have never been on a forum before and was looking for info on a gun my father had. It is a BSA with Martini action. The barrel says A. O. Niedner Dowiagac Mi. It has an old Fecker scope and I took off the front stock and the #634 was stamped on the bottom of the barrel. The stock also had the name T. Shelhamer 26. Can anyone fill me in on this. The gun is in great shape and shoots even better. Thanks! Craig123
