Thornton-Welles locking differential

[Tony Smith]

Whoa, slow down a little. The thread seems to have shot off on a tangent here.

The FGT Parts book is not talking about a 6x6/Tandem drive to convert a vehicle by utilising a Welles-Thornton rear bogie. The book is discussing an optional locking differential centre to be used in a 4x4 FGT.

C11Q-4299 Thornton-Welles Automatic Locking Differential (Optional, when specified).

The only other allied vehicle I can find reference to in WW2 having any kind of locking differential is the IH M-5H-6 6x6 trucks, with Thornton diffs. Are these the locking centres, or the tandem bogie arrangement? See: http://www.onallcylinders.com/2013/1...erential-town/

Curious the variations of Thornton-Welles and Welles-Thornton, which seem to relate to the US Supplier/Canadian Distributor relationship rather than any trade name or patent right (which seems to lie solely with Ray Thornton).

(Funny how this thread has sat dormant for 12 years and suddenly springs to life again.)
