If you ask nicely Michael Raue who run Dreadnought Hulls might indicate where he found his material. My suggestion is the Bundesarshiv Archives over in Germany. The material I have seen indicates it is just a lengthened Derrflinger with tandem rudders instead of inline ones. Mike Butts
Like Mike suggested, I would recommend you talk to the gentleman who runs dreadnought hulls. He may have plans for it or know where to get them. Chase
Thanks guys - good advice, I'll check with him. These battlecruisers were amazing ships (and were actually laid down, if not completed, like the Mackensen class), sort of a German Hood. 15" gunned EY was basis of 11-inch Scharnhorst class in WW2 (plans for later upgunning to 15" not carried out). Yes - Mike - a stretched Derfflinger with tandem rudders. Perhaps for better maneuvering or survivability? Best regards, P.
