Good question! A lot of USAF WC54's were taken off the airfeilds in UK and replaced with K2's just before D-Day. RAMC did use KD64's in Korea. As to 54's in British service I can't remember seeing any. Various private agency's, notable the American Ambulabce Service did operate VC54 in teh Western Desert in support. These are two official British photos, but notice the US maedical markings. I also have a picture of a 54 converted for use by the SLUs attached to US forces.
