The only Dominies that may have had "RAFCAW" markings were the three based at RAF Strubby, and were primarily used for the Aerosystems Course. When Strubby closed in 1972, they transfered to their parent base at RAF Manby, until it also closed in 1974. Twenty Dominies were delivered to the RAF between 1965 and 1966, and
AFAIK, all were originally in the same colour scheme, as shown above on the 1968 link.
