Daimler Dingo - Use by Royal Air Force

[David Molyneux]

Imperial War Museum photo CNA3557 is captioned "Two airmen of 2866 Rifle squadron RAF Regiment celebrate the end of the Italian campaign with a special issue of beer while sitting on top of their Daimler Mark 1 Scout Car".
The photo clearly shows the registration as RAF 90632; the photo is taken at an unusual angle and details of the vehicle are not too apparent but I think it is a Dingo.

Does anybody have any details of the use of these scout cars by the RAF eg numbers, contract or registrations; I am particularly intrigued by the registration which is very close to that of an Otter RAF 90640 also used by the RAF Regt and shown on IWM photo CNA CNA3672.
