I'm down here from Canada visiting a friend and he has his fathers old 52 Winchester sporter. It's a beautiful rifle but due to the way it has been stored, the barrel is pitted on the outside. I almost wept when I saw it. The serial number is 57792B. It may have to be rebarreled but I am certainly no gunsmith. He would like to give the rifle to his son, so I am kind of spurring him on to get the rifle checked out and stop the deterioration of a fine rifle. I am not sure how much he would be willing to put into the rifle but I have to push him a bit.
