Many thanks for your trouble. I think I'll let Mildenstein rest in peace now for a while. I don't want to  focus too much on one single person or one single issue. And there are so many doubtful cases. E.g. did you ever hear of Hans von Meiss-Teuffen? Aristocrat from Zurich, double agent in WW II, sailed across the Atlantic singlehandedly in 1948 and wrote a bestseller about it. Featured as a Russian spy in one of the first movies on flying saucers... and then, ver little is known about him. He's on my list too... Thanks again and greetings from Vienna. Robert Schediwy
