OK Andrew, it seems that everything points to the truck having been an airfield fire tender/rescue vehicle. What is unknown is where and by whom was the construction carried out and when? Was it purpose built for this role or is it a conversion?
The joint at the bottom of the windscreen pillar is a standard production feature. On the inside there should be a cover plate in the door jamb under which is a socket type joint secured with countersunk screws.
I had assumed that the aluminium gutter above the windscreen indicated where the graft of conversion sheet metal to original sheet metal took place but if there is no join there and the roof is one piece to the bottom of the pillars then that to me would indicate factory build.
Whatever its provenance it is certainly a unique vehicle.
As the fellow in Laugh In would say, 'veeery interesting!'

The 3 levers in the photo are standard Yankee Joe items. The two that are in the same slot are transfer case control, the forward one is front axle in/out and the rear one hi/lo range. The third one to their left is hand brake.
