Andy, to my knowledge the taller, rounded front fillet only appeared on the P-47N, The lower straight fillet appearing on the P-47D-30 P-47D-40 and the P-47M. That being said that picture defiantly looks like a P-47N type fillet. I know reps from Republic worked closely with the 56th FG. so maybe they were trying out the "N" fillet with the 56th. Only speculation though as I have never seen or heard of anything specific about the fillet. I'll have a look through my books and see if I can come up with anything.
