Thanks again for the links, Ed!
I got stuck on this Ju 87:

My best guess at the markings would be H5+IK, so 2./NSGr. 10. Is there any reliable info out there about where this aircraft was found? Some photos from this series have been taken at Köthen, others not. Some are labeled as Zwickau, so locations are a little unclear here...
