I think your suggestions are almost totally correct Hanno, although GM through McKinnon Industries Limited of St Catherines, Ontario, a GM of C subsidary since 1929, produced the GM/Chevrolet front axles and transfer cases having been requested to do so in '1939'. To quote from the company's own information:

'1939: World War II - The government called upon McKinnons to produce army 4 wheel drive trucks, percussion fuses, dynamotors, for 2-way radios, fire control mechanism, gyro gun sight motors, torpedo drives, elevating units for 3.7 anti-aircraft guns. Floorspace was doubled'.

In fact it was not the trucks per se but the transmissions.

I think what happened was that Ford of Canada adopted the M-H system for the very first prototype F15A, and then for the production F-GT, F30S etc. and GM fell into line. McKinnons supplied Ford with front axles for 4 x 2 and [I was going to say]] F60H but the 6 x 4 chassis used Ford front axles I think...someone correct me please! Well, that was the intention as the 1940 Ford front axle was not strong enough. However a) I seem to recall that Windsor imported the Dearborn COE front axle for the unpowered front axle chassis and b) used GM axles for only specific chassis as we have discussed before including early F15s and 75? 1941 Model F15As. The reason why GM fell in line was because M-H used Timken Axle Company, Detroit, components and GM's Pontiac plant also used Timken-Detroit components in their multi-drive GMCs as well as some export COE Chevrolet.Oldsmobile/GMC trucks. In other words, tried-and-tested components! I believe McKinnons arranged a licence to produce the GM-style transfer case and HD COE front axle in Canada.

Hanno as Search King of the MLU forum could you please direct me to the past thread whereby we discussed parts books evidence for axles and transfer cases for Ford and Chevrolet CMPs please?
