I'm going to the US National Archives next week, Monday through Wednesday. Hans Truöl will be one of the guys whose photos I'll be especially looking for, along with Bruno Wisniewski, Erich Fabiger, Werner Stille, and Helmuth Möbius. These seem to have been the "stars" among the Nordland and Nederland photographers.
So I may have a good quality scan of the photo before long. I'll let you know how it works out.
