The bottom truck has a Mid-east allocated Census Number. I am suggesting that it might have been to Demand S/M 2037, one of at least 6,847 trucks ordered as C60L/CC60L & F60L/ FC60L units.
This is a 1948 shot that my dad has in his collection from Jaffa when he was in the RAMC in what was then Palestine. Note the front-opening screen and British-style lights. The number plate appears to be Arabic. The front bumper is not a Canadian style MCP one.
