Ford US trucks for RAF, Egypt

[John Mackie]

The deeper you go into the Ford model codes the more confosing it becomes.
I was thinking about the letter D in the code C11ADF and wonder if it comes the model D used for the 15 CWT light truck , a model between the model C 10 CWT (1/2 ton) and model Y one ton..
One question, Does the C11ADF use the 15 cwt axle with full floating hubs amd a single join / partition in the rear axle (like the bigger truck diff).
.
The 15 CWT axle uses 4.1 ratio gears while the 1 ton axle uses a lower gear ratio and bigger brakes.
