I'm not 100% certain about this one, but I think it is 44-14377, which came out of storage at Walnut Ridge, AR in 1946 to be raced by Joe DeBona in 1947-1948 as NX33699, Race #90, "Magic Town." Modifications included a Merlin 66, wet wing and partially painted sliding canopy. It is reported to have been sold to the Dominican Air Force as FAD 1702 in 1948, crashed at Santiago on 2-4-50 and subsequently broken up for spares.

This should be NX33699, entered in the 1946 Bendix by Paul Franklin, but it didn't start the race. It was entered in the 1947 Bendix by Joe DeBona and finished second.

Actually this aircraft was ID no AMD 403 and then change to AMD (no FAD) 1703, number 1702 was P-51C-5-NT (serial 42-103730)and I can confirmed this after reading a Dominican Army document where IDs all their early Mustang. This Dominican Army official document was dated Nov. 15 1947
