Design Sketches for an Offensive Minelayer, 1937

In 1937, Germany was planning to build 4 units of a large, offensive minelaying ship. Though they were never built, these sketches outline the design.

Some of these images might be contemporary copies of others. Can you comment on differences/similarities between them?

There is an excellent page on this project at German-Navy.de.
