This is the second go at posting a reply..the first seems not to have gone through.

Basically, for a start see WHEELS & TRACKS # 8. Therein are some shots of the identical [more-or-less] VA 1939 Model or WA 1940 Model water carrier truck. These were assembled by General Motors Near East Limited in Rue Ptolmoees, Alexandria, Egypt and were originally in a WO census series:
L 39000 to 39515 Contract V 3352 LORRY 30 CWT. 4 X 2 GS/WATER TANKERS 266 UNITS GS AND 84 WATER 133-INCH WHEELBASE for Egypt.

GENERAL MOTORS WORLD February 1940 mentioned that the Egyptian Government had ordered 180 Chevrolets, and there is a shot of one of 50 158 1/2 inch wheelbase trucks, and 20 Station Wagons outside the Plant.

I suspect that this truck is one of those seconded to the LRDG, as suggested, and is a G/S truck...there were water tankers as well. Note shaved mudguards/wings and sand tyres. Note the removable canvas hood, and the front screen.

I would love a better version of the photos please for my collection...where did they come from? Mr Vanderveen got hold of some of the water tanker being tested.
