This is Lt. Frank H. Bouldin, Jr.'s North American P-51D 44-14495 "Dallas Doll" of the 352nd FS, 353rd FG. Lt. Bouldin named the airplane after Miss Christine Crisp of Dallas, Texas. He was officially credited with three confirmed aerial victories.
The aircraft flew 85 missions between October 1944 and April 1945 and was the only P-51 to carry the SX-I code letters. Bouldin flew the aircraft for 30 of those missions, completing his tour in mid-January 1945. Lt. Michael J. Martorella was then assigned the aircraft which he renamed “Jeannie” for his fiancé Regina (they married after his return from Europe). Martorella flew 18 of his 40 assigned missions in the aircraft including the Group’s final mission of the war on April 25, 1945.
A couple of these shots are with shadows disabled. I don't recall the lighting I used to get them the first time so I posted them as I likely cannot duplicate them anytime soon.
You can also see the comparison between the original and mine. I redrew everything except the nose art--which I kept, but cleaned up (h/t Dutchguy/Mus51).
