I reckon that these disjointed photos (i.e. scanned seperately though taken at much the same time) were official shots taken as they could be used for recruiting, training, etc. as well as being ideal for wartime publication when news must have been sparse. COMMERCIAL MOTOR and the motor cycle mags seem to have covered numerous despatch rider, RASC, ATS, Royal Signals, and other training establishments.
You will of course remember the Matchless G3 I posted a copy of with the Tillies.
