Not at the moment. We will be meeting with Reinhard Kornmayer in juli, and I will ask him about the specifics of this story. Forum member MRerick will be there as well, including video equipment. Perhaps we can even get a confirmation on video
The pistols were marked in Germany, by a German gun smith apprentice who came forward with this statement a couple of years ago to some researchers who, like Mr. Kornmayer, worked for german gun magazine DWJ.
