You’re right. Thanks. They probably didn’t have many E models left by 1944?
I imagine that you’re right about there not being many E models left in 1944, especially still flying combat missions.
Interestingly, although the “G” was the last model built, almost 2/3s (8,600) of all B-17s built were that model. And it was not even introduced until September, 1943. A remarkable testament to the ramped up manufacturing power we had as the war progressed.
