Concerning Edgar's last post, "Now were getting somewhere." No correction of looseness in a Parker will result in the breech face of the receiver or the barrel face moving fore or aft, in relation to the other. All wear and correction happens at the hook and the loop. The doll's head will not move in relation to the barrel face either. They are ONE part, fastened together. Any gap in the doll's head will be accompanied by a similar gap at the breech face, again, because they are one part, fastened together by whatever means. A doll's head gap will be caused by several different occurrences, barrel set being replaced, filing of the doll's head being two. Sorry, those are the only two I can think of. If the doll's head is a perfect fit from the factory, it should be a perfect fit a hundred years later.
It's not a wearing surface. Brian, please comment.
