Hi Nick,
Thank you so much, very interesting info. I was not aware of the post war accident of 42-103950. Just found a pic of 'KITTEN', #78, which indicates that her S/N was 43-25072 (43-02572), that I doubt. 43-25072 was a 100th FS P-51C, not 302nd and was salvaged on September 30, 1945:

Another interesting info is that famous 100th FS P-51C, 'Bernice-Baby' was 42-103555, which had two landing accidents on September 2 and December 6, 1944 with William T. Mattison and Albert L. Young onboard. See the small digits of 3555 on the air intake panel:

Does the accident report of 42-103950, #78 reveal the engine number of the plane? (32xxxx)
Cheers,
Gabor
