Used the relationship of the cowel cooling flaps 1 - 6 to map the wing fillet against points A and B. A is the common lower cowling panel mount line, and B is the top of the wing fillet. The white line is a common reference line from the real life photo and the center of cowl flap (3).
Ack-Ack's picture the top of the fillet arc stops 3\4 up cooling flap (3.).
Ack-Ack's Real Life Picture.Aces High's screen shot the top of the fillet arc stops 1\4 up cooling flap (4).
Aces High Screen Shot.By the way. The real life scoop under the cowel is bell curve shaped in cross section while the AH is rectangularish in cross section. Or at least using Ack-Ack's photo as a baseline.
Even in this photo the wing fillet stops 3\4 up cowel flap (3).
