Hi Richard;
The Canadian number on the vehicle is CH 4217674 and yes the bodies of the vehicles in view 1 & 2 are steel, which were manufactured by Dominion Truck Company, Kitchener, Ontario.
The picture from the Data Book is of a British built body which is generally similar to the A.E.C. Matador Medium Tractor body.
