Jan,
First of all, no one is an expert on any subject. They have just acquired more information than other people. When that information is shared, then others who have the information then become equally as 'expert' as the original person who had it. For example, I put everything I had on Erprobungsgruppe 210 into the Schiffer second edition of that work. Anyone who has that book now knows as much about that unit as I do - it's all in the book. I was just fortunate to do my research at the right time, and had the good luck to make contact with certain people, thanks to the generous assistance of others. And that, Jan, is the truth.
