This P-51D was the mount of Maj. Howard "Deacon" Hively while he was the CO of the 334FS, 4FG from June-Aug 1944.
It is the only 4FG P-51D to have been painted in olive drab. (At least that I am aware of.) The photo seems to indicate the black stripes on the top of the wing were painted over. I've presented it here just prior to that event. I can't decide if that's the right choice so please feel free to voice your preference.
Deacon served continuously from 1 September 1941 until the end of the war in 1945. His adventures (including the first shuttle mission to Russia) are too numerous to list here, but are well worth a look.

I just realized I forgot a few things before posting this, but they won't affect the input I am looking for from the group. Special thanks to Lyric1 for his help in interpreting the photo I sent him. I send one and he sends back half a dozen with very detailed observations. I don't know how he does it. Any errors are mine, not his.
SORRY FOR THE SLIGHT PIXELATION OF THE SCREENSHOTS.
