Sorry, Ed,...I missed your follow-up comments and questions up to now.
I thought the "Germany" stamps were applied to the lugers leaving Germany and not being sold in Germany. Since they were applied by DWM, I would venture to call them "export" stampings.
Import stampings I would consider such stampings as "Interarmco", etc...those applied by the company bringing guns into the US for retail sales.
Just a WAG...on my part...
