And from www.localhangar.com:
This aircraft started out in January 1945 as the C-54B Skymaster "Fat Annie" #44-9023.
In 1946 it was converted to its civilian DC-4 version. In 1962 N89FA was the ninth of
only 21 that were ever converted to the cockpit on top for car hauling thru the front
as "Carvair's". As of this date it is the last flying one of its type!
