First WW2 MCPs

[David_Hayward (RIP)]

I am just about finished with my book editing of volume 1 of the series. However I realised that I have no evidence as to which were the first Modified Conventional Pattern, or 'Commercial Chassis' as I have seen them described, trucks for the Canadian DND. I have seen a photo of 1940 Chevrolet ambulances lined-up..these were 1500 Series 2-ton chassis and from my tables of '40 Models these would be Model 1543, and photos I have show that there were also GMC versions, Model 9543 in theiry with the same Chevrolet engines!

However additional information suggests that there were also 1940 Ford C01Y 1-ton 122-in. wheelbase and C091T 1½-Ton 134-in. wheelbase. Can anyone confirm/add to this list please?

Incidentally I found that GM of Canada supplied imported US GMC AC-704 178-in. wheelbase chassis for fire-fighting vehicles [for RCAF]. I had not noticed before that GM of C imported Pontiac-built chassis as well as engines.
