It appears to be an early Series IIa. The models before 1968 that had the individual wiper motors in the windscreen frame.
The body on the rear is a workshop platform. Depending upon what fittings it had it could have been anything from a mobile office to a fitters truck. There is more information about them on the http://remlr.com/lrpr_raeme_ade.html site.
The diorama is the Vung Tau Ferry (HMAS Sydney III) with some nice little Mk3 Inters!

You won't find me on: faceplant; Scipe; Infragam; LumpedIn; ShapCnat or Twitting. I'm just not that interesting.
It would be a Series 2a 4 cylinder model 109 inch WB "Truck 3/4ton ", and it has the military body type of a workshop vehicle of which there were many variants,it is painted in UN white, but appears to have a light camo pattern on it, the last pic is of the HMAS Sydney, a converted aircraft carrier which was used to transport vehicles and supplies as well as troops to Sth Vietnam during the Vietnam War era 1964-1972, the pic shows vehicles being unloaded in what could be Vung-Tau harbour (Sth China Sea)
