Christoph, What a Memory you have!
How on earth could you find 2 posters that were not in Marion's collection! And you are correct, I had not ever seen the collection. Pretty Awesome!
And the name Dr. Zenker had definitely slipped away from me. Thank you for sending me to correct place in the thread.
With all of our new knowledge I want to go study everything over again. Not sure when though. Saw the names Mary mentioned and want to look in the 6G document you sent for them.
I am on way out and when return will get the 2nd and I think last, Bitterberg response to you. You will see there is a document that maybe you do not know about mentioned. It was never sent to me and I did not want to be too pushy and figured one day I would get to Siegburg and find it - that was over 3 years ago! I am so curious to know if you know of it. But now we must wait I am out the door - well almost.
