Yes you are correct Rafe35, he did not fly the P-51D, and did fly the P-47D.
The book " THE LAST OF THE SCREWBALL ACES " by Troy White, is the best reference out there for info. on The Kidd. When he went down near Mostar, he was not flying his assigned a/c, as he would not take his shots needed for the shuttle mission to Russia. Another pilot was flying his assigned a/c. He was able to fly a back-up role, at the last minute, and when no one turned back with problems, he tagged along anyway.
Here are the planes assigned to him according to the book....
P-47C s/n 41-6484, QP-L "The Missouri Kidd-SHO ME "(assigned this a/c in late October or early November of 1943. This a/c crashed on December 2, 1943 killing F/O John P. McNabb)
P-47D s/n unknown QP-L (he flew this from Dec.1943-Feb.1944)
P-51B-5 NA s/n 43-6946, QP-L
P-51B-5 NA s/n 43-6646, QP-L
P-51B-10 s/n 42-106924, QP-L " Salem Representative "
