On the Links Page of the web site, lower right corner, there is a link to “The Library”. In here I’ve posted most of the original German source documents I’ve gotten to support the EWCG. I have a number of other documents including the Enigma manual here at the house I have to scan. Then they will be part of the library. You can download these at your pleasure. If you can read German in Fraktur script, these should be some light reading in front of the fire some evening with a cup of cocoa, or a good single malt. Enjoy.
