Hey David,
Drawings like that just blow me away. I started out hand drawing in my early drafting days and I had seen other drawings with that kind of exceptional details. It's so sad that the age of computers and 3D modeling have made drawings like that obsolete. But to me, they will never be out of date.
Let me get some more photos. That is a 50+ year old drawing right out of the design center at Boeing. My uncle has dozens and dozens of aeronautical patents.
