They all appear to be CI conversions. I can't remember the name of the Ford version - was it the Wayfarer? There was also a Bedford version called the Bedouin which was usually mustard colour. I seem to remember the Fords being pale green, whereas the Commers were always white with a green stripe and back panel.
Although by the 1970's the Commer was the most dated of the base vehicles, it offered the most space in the back.
