Craig, I could not defend the statement in the same way we would defend a thesis or dissertation. I have heard claims of having seen reference books with this information from M.Morris, take that for what it's worth. I also had a conversation with a German gentlemen in April of 1980 near the Oberndorf facility. He claimed to have been such an inspector for the Waffenampt and that they each had individual numbers. Could as well have been the beer talking as anything else... So I best amend my statement to reflect "hobby speculation" for the moment. Welcome to the Forum. Glad to see you here!
