Hello again!
A little fallout from my AU, represented as realistically as available sources allow:
1. Spähkreuzer 1938
This image represents the final design as laid down in 1941; as there seem no original plans of that type left, I choose a drawing from a russian site as source which showed the most details. This unfortunately does not mean they are all correct.
For the next two, I found very good reference drawings, also on a russian source (the forum of tsushima.su, all in Russian, finding these pix was pure coincidence), scanned from some German book, don't know which one.
2. Geleitboot 1941
3. Zerstörer 1945
Greetings
