Hmm. I think the thing that's throwing us is the guy in the last photo. The 'board' that he is holding certainly looks like an X-Ray film cassette - they haven't changed much over the years, even now that most have gone digital. Also, I'm not sure that that is a 'Stuka' he's sitting in, just going of the size of his seat. But he is wearing a seat-type parachute. Obviously the 'Stuka' must be linked, due to the badge, but there was no mention of JU87's in the lists at the other site, although there was one out of sequence, not shown.
I honestly don't know!
