Well, I got the stock off and there are absolutely no cracks or evidence of repaired cracks of any kind on the interior or exterior. The wood in the wrist area is as sound as can be. So I am guessing that someone had the screw installed as a precautionary measure which is too bad but I guess it worked. As I mentioned earlier, the installation was tastefully done. It is a round thin brass headed screw and on the other side it is a round brass sleeve with internal threads that has been inlet into the wrist. This is a Canadian Iver Johnson, built at the Cooey plant in Cobourg, Ontario but that shouldn't have anything to do with it, unless someone requested it from the factory that way. Oh well, I guess I shall never know for sure. All I know is the stock is in very nice condition.
