ARN infomation Needed Please

[Plushy]

Hi everyone ,
a mate found this on his travels and the owner is interested to find out the history of the vehicle can any one help ?




Its a very faded green apprently but could it just be a discoloured RAAF blue ? It also has extra plates on the chassis like the tipper`s do but has never had rams fitted .

Thanks for any info Gents .

cheers Plushy
