There are "factory drawings" and Factory Drawings. What I mean is that most of what you see in publications might be general arrangement drawings which originated from the different manufacturers. These are nice for modeling and getting a general idea of what an aircraft was like. This type of drawing exists for most Luftwaffe types I have ever taken the time to run down (exception Hs 127, has anyone ever run across these?). These were used for sales pitches, training, studies, etc. Airplanes are not built from such "factory drawings". The real Factory Drawings that were used to build a/c at that time consisted of thousands of small part drawings, followed by sub-assembly and assembly drawings in a number of levels. there was also a great deal of manufacturing process documentation on machining, welding, etc.etc. Much of this material is missing, but a lot, millions of pages exists in both hard copy and microfilm form (IMHO probably about 50% of the original material), you just have to search for it at the various archives.
