sabredog - there's a whole sequence of Prestwick during the war
here
I took a flyer on Böblingen as being where the Klamm was manufactured and I guessed there might be one still around at the end of the war. I couldn't match any of the buildings either although they seemed to be in an arc - which they were at Böblingen. Is the seibel the 3rd in-line? My tentative identification was a ME Bf108.
For your challenge - somewhere in Brazil?
