My point was actually just a reference to the fact that Stoeger, back in the 1920s, registered the trademark of 'Luger', rather than sticking with 'Parabellum Pistol' as the manufacturer referred to it, and had the pistols they imported stamped with 'Genuine Luger'
Hence Umarex and Gletcher can sell you a P08, or a Parabellum, or a Parabellum-Pistole P.08, but not (I think) a 'Luger'.
