@Raxar: I know what you mean. Even to me, knowing where the turrets were, they appeared reversed. I was waiting for more opinions on this matter, but I think it's better to change.
Anyways, everytime I sit down and go over my pictures, I find more details and little things I missed the last time. Shows how much I have to learn. Here's an update for the 1929
Königsberg:
In 1934, some changes had been made to the ship: Superstructure had been enlarged, torpedo caibre increased to 533mm, two additional 88mm Flaks and four 37mm Flaks installed to counter the increasing air threat and a larger crane for the soon-to-be-installed aircraft facilities.
