Thank you, Evgeniy !
I had already found the chimneys due to their shadows;
and, by intersecting those lines, we can position the tank to within 30 meters.
Now, this other photo has an interesting building with its own chimney, at the right:
And there is a large train shed at the left. This is easy to find, it still exists today, although its roof is different now.
The tall building and the chimney no longer exist, but I found them in one aerial photo;
I can see them better in your big photo, thank you!
The result : the two photos were taken very near to each other. The Tiger has turned around and moved.
