A bit of a riddle here:

It shows a Portee repurposed as a GS truck during the liberation of Leiden, May 1945.
But this is a Ford, and as far as I can tell from David’s listing above only Chevrolets were built as Portees? It is not a converted F60B, as it has a Cab 13 (see the man standing on the left side of the truck).
