Sorry to out-do you, Supah, but my original version (1st profile) is uglier than yours AND the background colour is worse:
My only excuse is that it was done on a 386 with PhotoFiltre.
I will be redoing it with the new template. At least we agree on what it should look like.
CAM: The difference between P-51D and -K, IIRC, is mostly the prop. Ks had an Aeroproducts prop in place of the Hamilton standard. However, most of them were incorrectly balanced and vibrated so they were replaced by HS models.
I think the other "hood" is not -D or -K relevant but depended on where the aircraft was produced. I might be wrong on the specifics, though.
