You might be interested to note that under the WD Specification Spec.36A there were various types of WD standards for vehicles that included 6-wheeler 30-cwt and 3-ton lorries. However in 1937 Spec.36B introduced for the first time the concept of 4 x 2 3-tonners, ostensibly for Egypt. This at a time when the 30-cwt 4 x 4 was going to replace the 30-cwt 6 x 4. However, what was not appreciated at the time was although the 4 x 4 chassis had distinct advantages over the 6-wheelers, the latter chassis was in the end required for longer bodies: breakdown, stores, pontoon, etc. This shows that the wind blew from one direction to the other in the WD Mechanization Board. Of course the 4 x 2 3-tonner were required in quantity but by late 1939 the advantages of 4 x 4 drive were evident with the Canadians initially calling for Marmon-Herrington conversions to suit. What actually resulted was of course history!
