Some comments about the "My Gal Sal" from the Aerovintage blog:
B-17E My Gal Sal Hung with Incorrect Propellers?: Well, yes, eagle eye Patrick noted in a recent email that rare B-17E 41-9032 appears to have had wide chord "paddle blade" propellers installed prior to it being hung from the ceiling of the National World War II Museum in New Orleans. The wide chord props were used on the B-17F and B-17G to provide increase performance, but the earlier B-17E had visibly narrower chord "broomstick" props. I have no direct knowledge, but would suppose that the museum needed to replace the belly-landed bent propellers that came with airplane with undamaged propellers, and it is much easier to find the wide chord blades (same as the DC-3/C-47, I believe) than the early and rarer narrow chord Hamilton Standards.
For purists, the B-17 propeller hub was the 23E50 and the early narrow chord blades were, mostly, the 6153A-18 blade and wide chord blade was, mostly, the 6477A-0 blade. Variation seemed to have existed, but this seems to be the standard. The 1946 CAA Limited Type Certificate for the B-17F and B-17G, but the way, list both blades as usable with that propeller hub on the F and G.
