Hi Tom A.,
Author C. Kenyon in his 2nd. book, "Luger - The Multinational Pistol" on page 80 states that "W.D." stands for "Werft Division". Similarly..."M.D." for "Matrosen Division".
Does he agree with Werft Danzig, now ?
Regards,
Pete... <img border="0" alt="[typing]" title="" src="graemlins/yltype.gif" />
