Nope, sorry guys, but I've played with a lot of Lugers. The tool shown does nothing that is "model specific" to aid in disassembling one of these pistols. Oh, it does have a screwdriver tip on it, so maybe one could call it a "takedown tool", but it performs no specific function that a normal screwdriver could not. The original German blueprints (which, unfortunately, I cannot find online, but have seen personally) call it a "magazine loading tool".
