RAF Crash tender identification

[Larry Hayward]

Hi folks can anyone help ID the Crash tender?

Behind the two Free French Airmen in black overalls, who have just landed at RAF Christchurch in a stolen German Bucker Bu131, in April 1941, is the station crash tender but can anyone confirm what type it is and supply a clear shot of the same type of crash tender? It looks very much like an Albion AM463 from the radiator, which is commonly seen as a refueller and an ambulance but hardly ever as any other version, though Bart's book does say it had other uses. However the overhang of the cab roof over the windscreen does look more 'Crossley'. Someone who was based at Christchurch at the time thought that the crash tender was left there by the prewar Flying Club but I don't think it is a civi model.
