OK: back in the office after a very pleasant trip to the Yellowstone region of the USA. Even the drive home along Interstate 90 was pleasant - much easier than 20 plus hours in airports and aeroplanes (sorry 'airplanes'!) Fantastic scenery!
Dianna, to answer your questions:
112723 and 170437: I hold no records that indicate overseas service for either of these two vehicles.
The 'personal' sign on the side of the truck: these are often Troop/sub-unit signs for which there is little, if any, record. The only way you might crack this open is to locate the perpetrators! I agree this may be an RAAC unit, so why not try putting the image up on the 3Cav/3/4 Cav and 1Armd Regt websites/forums, and ask? Can't do any harm, and you may well find out some interesting info about the 'Bods' involved. Don't think 8/13 and 4/19 have web forums.
Bob: ref the Inter (the original subject of this thread):
171446 and 171415 both had service in South Vietnam 1966-68, both returned to Australia in late 1968 (and apparently, both 'processed' along the rebuild line sequentially as well).
