I'd forgotten until I was reminded by another reference recently that XR 511 was one of four Wessi detached from 72 to the Sultan of Oman's Air Force (SOAF) from about March to December '74, to "assist" in the Dhofar War.
Unusually for such occasions - crews were all regular RAF - the aircraft were repainted in SOAF camo colours and with SOAF badges. Can't find a photo of 511, but this shows the paint job. (this one is actually XS 678)
