Yes, that is one of my images:
This was indeed built on a Ford F15 chassis but there was also an Australian Chevrolet counterpart which differed in detail only. They were of coachbuilt construction using both steel and timber and were very unusual in the seating arrangements. The front seats were leather and folded all the way back, the rear bench seat (for the officers) was a leather bench seat which could be folded back too to form a sort of camper arrangement. There was a canvas side annexe on the left hand side and very uncomfortable fold down seats in the rear for others. The spare tyre was carried flat in the rear of the vehicle under a shelf.
