[Lugerdoc]

The luger receiver wrench shown is one of 5 made for me 25 years ago by a California machinist. I don't know what he intended by the cross, although he was copying a photo of a Swiss tool, and the Mauser Banner must have been added later by a subsequent owner. The verticle steel bar does in fact fit between the "forks" of the receiver, mainly to assure correct positioning of the wrench. I have used mine to change close to 100 barrels with excellent results, although the threads in the brass lower block finally stripped and I had to drill the holes all the way thru and use nuts on longer screws, as a repair.
