The mystery deepens. I have never seen anything like the PTO mounted above the transfer case. Is it secured to the TC and driven from it somehow? That would be a complete novelty. Or is it a separate unit that just happens to be mounted there?
The rest seems to be standard Yankee Joe cargo truck configuration except for the strange bodywork. The windscreen surround is standard inside and out up to just above the hinge mounting.
The truck is definitely not an earth borer, pole setter or M6 bomb handler and I don't believe it was a tractor unit. That still leaves quite a number of possibilities as these trucks were used for all sorts of odd tasks.
Nomenclature, data and shift plates would have been mounted on the header board above the windscreen. I think you can see where some have been removed.
All in all an intriguing vehicle. If the PTO is an original factory fitting that may be the vital clue. If it just happens to be sitting there, my guess would be cargo truck with post war body grafted on. The pintle hook and bumperettes point in that direction.
