Hi, Chuck:
here is what the Academy B-17's look like.
I built this B-17G for Bish's 8th AAF GB a couple of years ago. It was reboxed by Airfix, but it originated with Academy and is identical.
Here is Academy's B-17E:
I don't know if they're still available, but Academy did produce a nice version of early Forts, the -B, -C, -D and a combination -C/D. The B-17D carried markings for "The Swoose."
Bish is right. With the B-17G, both staggered and unstaggered waist positions are indicated on the interior fuselage, and you have to cut open which option you want. It takes a lot of fiddling, carving, filing and sanding.
For comparison, here's my take on "Memphis Belle," using the Hasegawa offering.
I still have several Hasegawa's in the stockpile, and they are still good kits, despite their age. In some ways, I think the Academy offerings are a little "heavy" compared with Hasegawa, which is sort of "petite."
In addition, the side nose windows from Hasegawa are incorrectly shaped. Academy is much better there, but Academy's engines are atrocious representations. Hasegawa is much better there.
But as you say, the price for Hasegawa's Forts is astronomical compared with what it once was, and Academy is much more reasonably priced, usually.
Good luck with your Fortresses.
