G'day David,
http://www.awm.gov.au/collection/024625. Mine was definitely a militarised version as can be seen by a slightly younger version of my truck. Same windscreen modification. The description says "Australian Army"
The details of the photograph from the Australian War Memorial collection appear below
P.S I found another photograph from the AWM of a Chevrolet with the same type of windscreen.
Kind Regards
Lionel

Description
WESTERN DESERT, EGYPT. 1942-07-22. AUSTRALIAN ARMY CANTEEN SERVICE MOBILE CANTEEN. THESE 3-TON TRUCKS STACKED WITH GOODS PLY UP AND DOWN THE REAR OF THE BATTLE AREA SUPPLYING THE WANTS OF THOSE WHO HAVE MONEY. NOTE THE NAME "GLORIA" ON THE FRONT OF THE TRUCK. THIS IDEA OF INSCRIBING A GIRL'S NAME ON A 3 TON TRUCK IS, IN A WAY, A DOUBTFUL COMPLIMENT TO HER MEMORY, BUT IS A WIDESPREAD PRACTICE AMONG BRITISH TROOPS IN EGYPT.
