rollbac,
You didn't post photos, so we can't see the crossbolt. If it only protrudes a little, it may have been set up that way; if the top lever is right of center, it likely was. New guns were often set up this way to allow for wear. The crossbolt on the gun in Wertgarner's website is protruding slightly, so it seems that is their way. Any of the gunsmiths in the Trade Directory of WAIDMANNSHEIL( one of the publications of the German Gun Collectors Assn.)can accomplish the work for you.
