I hope everyone understands that I do not want to stray too far from the CMP theme but there is really a lot of inter-connection between the pure CMP vehicles,

Bill,
Actually, Ford/Marmon-Herrington and CMP vehicles are related. This is confirmed by the quote from the AEDB Design Record below, and also by the picture I found in a pre-WW2 Marmon-Herrington brochure. Said picture shows a short wheelbase gun tractor prototype built by M-H for the Canadian War Department on a Ford COE chassis - this is what I believe the predecessor of the CMP Field Artillery Tractor. So please dig out those original Marmon-Herrington catalogs - like you say they are bound to add to this field of research!
Regards,
Hanno

Immediately after the war was declared, the Ford Motor Company of Canada were charged with the responsibility of developing a 4x4 truck for army use. Obviously, they had very little experience in this field [...] Consequently they went to the Marmon-Herrington Company, Indianapolis, who in peace time supplied conversion material to convert Standard Ford 4x2 trucks into 4x4 models for various commercial peace time usage. [...] these joints were unsuitable [...] [the weight of the more or less cab over engine design and heavy army wheels/tires put too much load on the front axle joints.] To solve this problem, "Bendix-Weiss and Rzeppa joints were chosen by General Motors and Ford respectively [...] [They later realized that the "Tracta" type was better but they were already tooled up with the above types, so left it as it was.] (The AEDB Design Record, Vol. 4, p. 27).
