ILLUSTRATED SPARE PARTS LIST for BRITISH ARMY
3 TON 4x2 - 134" W.B.
SUPPLIED ON SPLY-MECH. 2606 ONLY
BUILT FOR BRITISH WAR DEPARTMENT
Ford Motor Company of Canada Limited
SE 130 Issued October, 1942
There are no pictures in the parts list of the truck itself, but it's right hand drive. It can't be a FC60L, as that has a 158" wheelbase. Plus, like Mike said, this manual has a section at the back listing Marmon-Herrington front axle and transfer case parts.
Who can shed any light on this? (Over to you,

David)
