Date these photos please?

[David_Hayward (RIP)]

Can we date these photos please? I have lost the confirmation when my PC crashed.

Note the 1938 15-cwt. GS truck in the background in the May 1940 parade...this was chassis number 815312825 originally D.N.D. Z 38-1-20 allocated new to ‘B’ BATTERY [KINGSTON, ONTARIO]. I cannot believe after all the evidence that the truck in the February 1940 photograph in February 1940 in Delville Barracks, Cove, Hampshire with a broken right headlamp and Ontario number plates was other than this truck. The Seaforth Highlanders of Canada, who were brigaded with the PPCLI, used it. Its driver at the time was Private George Kenyon. This truck, repainted into service green and allocated the WD style number CZ42.... was photographed and its picture appears in Dr Gregg's book being viewed by the Earl of Athlone.



These must be Ford F15s....but when? June 1940?
