Here are a couple of shots of British Grants of the 3rd Carabiniers in Burma. There is not much in the way of markings on either, the tank in the foreground has the name 'ANGEL' painted on the door just below the vision slot. They would appear to be painted 'Jungle green', which is a standard dark olive drab. They may have Tac signs, Circle, Square, Triangle painted in squadron colours, usually on the turret. I have seen at least one Lee with a large white allied star, but this, I think was not the norm.
