G'day Sam Ball
There is a possibility that it is Ex Military, BUT, it was probably a GS, and has had the rear tub removed and a civilian Ute cab and panel fitted, and a steel dropside fitted, also has a Holden Motor, and a bench seat with a console fitted, would take a fair bit to return it to Military spec, but, if you only want a series 2a for general use and not a Military one in particular, that might be worth haggling over
