Fantastic stuff, lyric, thank you!
Images of the right side of tail especially helpful, I wasn't sure if the heart was duplicated there. I can't replicate the name banner "Pudgy" at that location though - the B-17 skin map has only the left side of the tail turret and that is duplicated for the right side. So we are stuck with the "Lorraine" banner on that side, except the name is backwards. The reversed letters are evident only at very close range though.
I've made adjustments to the size and location of tail serial name and ID letters per the original B&W photo I posted.
The photos you've found also definitively answer for me the question about the black leading edge de-ice boots. I won't include them. While most color profiles I found show these, I suspect these are cases of the artist adding extra elements to make the work more visually interesting. I think its likely the Fort arrived in theater in 1944 with these boots in place, but they were removed in due course - so they would've not been present by the time the nose art and number of missions matched the more famous images we see of the aircraft.
Interesting too how the right side of rudder is missing a patch of color. Wonder if the rudder was damaged/repaired after it was painted red?
