I'm looking for schematic drawings and blueprints of none-build u-boat type VIIC/42.
E.Rossler in his book "Geschichte des deutschen Ubootbaus" Band 1 provides the drawing but of very poor quality.

I'm also searching for schematic drawings of project u-boat type VIIC/43.There is only a small piece of the blueprint in the Rossler's book but I would like to have a more complete one.

Does onyone know where I might find better plans/blueprints?

Best regards, Alex
