Hello Adam, welcome to the Luger Forum!! OK, so we know it's marked DWM, and the serial number is 483h. So far it soundslike a military designation, but the 30 Cal. barrel is confusing. Are there any other markings on it? Some photos would be nice!!
My first Luger was a real dog!! I played with it for a while, then sent it to Ted for his expert work and now it's one of my favorite shooters.
