Roland if you look on the Jackson site they have some Renault 6x4 tractors which use a similar Berliet cab to the Transcontinental (or 'H' series as it was known within Ford), but I don't remember Ford ever supplying any when I worked in Special Vehicle Ops who would have been involved with Ministry sales.
The Transconti was a real multi national mongrel, engineered in the UK, American driveline (Cummins/Fuller/Rockwell), French cab and built in Amsterdam.
