Another RAF Q2 Van photo, found by Mike Kelly in the State Library Victoria.
It is captioned: "A visit to an Australian Mosquito Squadron of the R.A.F. in Great Britain. Shows air crew on truck going to briefing. Date [1944?]"
Seeing the markings on the tail gate, I reckon it is in service with the Second Tactical Air Force (2TAF) somewhere in NW Europe rather than in Great Britain?
