Built as C-74 USAAF 42-65406. In 1949 it was converted to the YC-124 prototype. Flown to the original USAF Museum in 1957 and put on display in the outside aircraft area. It was deemed too large to move to the current museum site and was donated to the base fire department and expended (scrapped) circa early 1970s. This a/c was not reserialed 48-795 after its conversion. 48-795 was the first new build C-124A constructed.
