I'll have to go through my old magazine stacks, but I'm pretty sure theres an article or two from "Air Classics" in the '90s which had the B-17E. I seem to recall one having been found pretty intact in a junkyard, and another issue with a photo spread of early-model 'Forts.
I'll give it a good going over this weekend if I get the chance and get back to you, most of those issues havent seen the light of day since before I went to basic.
