The only way to find out anything about it is if any photographs exist of it in the net or with some military units that websites for past/serving members, failing that when you get hold of it you may/may not want to sand down the door panels or the sides of the wings for any markings that could be lurking under paint, so it will be an anxious/sleepless time until in arrives, this is from Remlr and it's not showing any indication of any images
112-498 88 1963 - Series 2A 6005 Truck, Utility, 1/4 Ton, GS 25143261C 24303524A - 750x16 Vic. 18.08.77it was disposed of in Victoria on the 18/8/77, and just for interest sake it's 3 digits from my 112-501 which went to Sth Vietnam with 1RAR in June 1965, the first deployment of Aussie troops into the conflict, ? so maybe just maybe it could have went over as well, cheers Dennis
