It appears that the organisers of the “Gathering Of Eagles” are asking questions about the veracity of Herr Dulias' service career. See the following link (10th post)

Gottfried Dulias may well be what he claims (though personally I doubt it) but the lack of evidence doesn't help his case. Why doesn't he contact the Bundesarchiv (WASt?) and get his service record (I believe most officers records survived) and he could then prove his many detractors wrong.
