Roland and I am have had last Sunday the trip to Hollenstedt. I only can second what Kai already has said. Günther Heckmann is a very nice and courteous person and we have had some very enjoyable and informative hours. In respect to ificah and the nice booklet for resonable price we don't have taken pictures but it's planed to bring the pictures from ificah online visible but this can take some time.
What I can add is that the display is arranged with care and love to distraction. Very intersting!
