I'm reasonably confident that the traditional view of the A-6/U derives from "Warplanes of the Third Reich". God knows how many secondary sources have repeated the description and sorting it out would require access to the original documentation. I don't have that & hadn't read the bit about there being no such thing.

I am sure however that I too have read in more than one place that the gondola was removable at a fairly low level.

Given the photo in question, I suspect that not much more can be said than that it is a Ju-88 maritime recon aircraft based on an A or D sub-type, not a T-3 as captioned.
