I just now found this, and I thought in view of all the B-17 forum topic discussions going on, that it might be useful and informative for future projects. Some excellent period photos and some of the restored Memphis Belle. I hope you enjoy them. The B-17C/D and B-17E photos are especially interesting.

I also found a link to the EAA's B-17G, Aluminum Overcast, which has the history of the aircraft from when it left the factory to the EAA. The operating manual for the B-17G as operated by the EAA is also included, and makes for very interesting reading.
