Joe: If the job is done correctly you would have nearly full contact. By blacking the hook and reassembling the barrel to the receiver you could determine the degree of contact and possibly see the weld/ base metal line. I don't see why it would be important to know how it was done as long as there is good contact. The traditional way of course was to dovetail a piece in and fit that down. I don't know that would be a superior fix, though, just more traditional and the way it was done before TIG.
