Wildchild,
Negative sir. The revellogram B-17G is a B-17G, early to mid production. The late F, early G thing can get confusing. The last 86 vega produced (dont hold me to who built them) F models had chin turrets. Somewhere along the line it was decided that with the chin turrets being added there was no more need for the cheek guns, so they were deleted. However, they figured out that was a dumb idea and added them back in, at the production level. I've seen plenty of pics of G models without either enlarged cheek windows or bulged cheeks, pretty much telling you that is an early G. But alot of these had them added in the field anyway to bring them up to date. The 86 F models I mentioned had the bulged cheeks and chin turrets, but the nose cone was the pointier F model nose cone. And I think (dont quote me), the bulged cheeks on them, were reversed position of what the G had.
