With due respect, the base vehicle is a WWII vintage Bedford QL series 3 ton 4x4.
That being said, I cannot truly solve the puzzle but I can speculate that it has received a later cabin, body and front bumper assembly. As well, I would bet the original petrol motor has been replaced by some sort of diesel, a Gardner, possibly a Deutz or some such.
I don't like guesses but I will have to guess it was based in the Netherlands.
