Hi to all, The guide Miles chose to modify is a pretty neat and unique design? It has more full circle bearing area on the recoil lever end and I have never seen such a part on a war time Luger or before? I am assuming it is new Mauser parabellum or perhaps Swiss, as those are the outfits that could, would, most likely make something like that? Does anyone know for sure the origin?.. I would like to know myself... best to all, til...lat'r....GT
