I do not own one of these either, primarily because of the same questions that you are asking. There are many very good fakes out there. In my opinion the fit and trim on this helmet is questionable; the eagle does fit tight, the Wappen does not conform to the helmet shell, and the side edge trim doesn't mate properly. I also noticed that the interior colors seem to be reversed. It should be green on the front visor and black on the neck guard.
Just my opinion.
