Australian CGT mystery

Now, if Sid used a standard Marmon-Herrington transfer case to start with, would your reasoning be the FGT was developed before the F15A?

Yes I think that this might be right!

The drawings in the books show that the F15A differed substantially from the other Ford multi-drives...nothing like each other in fact! I am inclined to believe that the prototype 15-cwt used a M-H transfer case, Ford rear axle and GM front axle. This possibly gravitated to production with a two-speed transfer case with PTO, since the PTO was required for the winch on a GT, etc. Don't forget here please that the DND papers show that drawings were sent over late in 1939 of the Guy Quad-Ant and the MCC GT, as well as pattern trucks. It was their cab design that Swallow wanted because it satisfied WD Spec. 36...Windsor then adapted the British design to use Canadian sheetmetal and hey presto! A design that satisfied the WD specs. I believe at this point that the GT led the way to production, followed by the other chassis designs and also the F60H. The F15A was a 'development' of the basic design possibly after consultation with Oshawa and as no PTO was required a different design of transfer case was obtained for general expediency.

The next step is to see the drawings of the C15A case! Anyone got one please?

Oh! On the above basis the F-GT begat the 3-tonners! That would fit in with the 3-ton rating?
