OK...Question time!
Below are 3 photographs. I know the 1st one is U-69, just a wider angle (none cropped) version. This is the third size of this photo....is it still even bigger? (not much of a question here), just curious.
The real question: The second photo???
My thoughts....could be the 69...
Wind deflector, breakwater & net cutter in place. Framework of shipyard, suspiciously like Krupp Germania Werf, Kiel...
Best guess from measuring on photo, there are 20 vents on top, unknown on the bottom (obscured) Could make it - 69,94,95,96,97,201,205 (unless I am wrong about the yard, then 357 might come into play). However - 201, 94 & 96 had no deflectors upon construction...if I am correct.
This leaves 95,97,205 and the possible 357 (see 3rd photo from Subism, claims to be 205) This could, and I am not sure, have 21 vents...any guesses?
Anyway, if you feel like weighing in on it, let me know & thanks!
Cheers!
