I can tell you where Monty's Rolls is. There is also a picture of Monty in a small tourer in Jersey, that car is still in the Island. So no reason why Monty shouldn't have ridden in a Jeep. Would make a lot of sense in the war zone any special vehicle= special target!. Rommel learnt that one the hard way in France.
Obviously the gentleman took a lot of trouble over the joint, so is worth keeping as conversation piece.
Any chance of a picture?
