Thanks falo!
I have first 2 of those pics too on my hdd. The deck with torpedo rails looks interesting. Some information i've found about VIIF boats:
-It's 10,5 meters longer than VIIC, and the hull is 1,1m wider than VIIC. (in 1:72 scale it's 14,6cm and 1,4cm) That means the VIID conversion kit is not correct by size. Maybe with new deck one might get close enough...
-U-1059 didn't have a schnorkel. U-1060, 1061 and 1062 had schnorkels.
I've been working last 15 days now so i haven't got energy to search the diagrams or blueprints... But i will soon as i get some free from work.
