Hi Tony
I always understood that the Bedford QLB LAA tractors as in your post were actually sent to Australia and not refugees. From what I remember they were assembled at the GM plant at Fishermans Bend. It is highly likely they left the Vauxhall factory in Luton in the same colour as all other Bedfords coming of the line, ie same as the then current army paint regulations in UK.
Regards Richard
