I can add this to my pile if you like, but it might be a while before I can get round to it. Ideally I'd like at least one photo of the original WW2 plane though.
The fillet was sometimes retrofitted to earlier bubbletop jugs so it is not a good indication of which version of the plane is being photographed. Also I think they fit them to all currently airworthy P-47D warbirds for safety reasons, whether the original WW2 plane had it or not.
