more information. The fellows mother got the gun when she was 12 and he is 81. Under the fore end there are stamped the following, a dominant d v,then to the right and slightly higher there is a B in a circle,then to the right and slightly above is an I in a circle, about half way to the fore end clip there is an A. The fellow is somewhat of a history buff so he would love to know about his mothers 410. He thanks you all for the effort. I am only a little younger then him and I have converted him into a full fledged gun nut.
