This is the only image I have, I suppose you already knew it (Click on it to enlarge).
For warships the Weyer's Taschenbuch der Kriegesflotten was widely used, and still today is sold. I bought last year one example in Vienna, the 1943-44 edition. If you want more precise datas of it, I can provide samples.
I like your project, I would prefer to have a good, realistic looking printed manual rather than any other format. Cheers
