Sakijoe; If it can be determined that its' a Norwegian Luger tool, I would be happy to trade a Weimar tool for it
But I really don't know what to look for, as I have never heard of Norwegian Luger tool..
If made by Kongsberg, I would expect it to be stamped.
klaus 3338; are the two to the left on your last picture norwegian? Is there any markings on a norwegian tool?
