Thanks Diana - your information pointed me/us in the right direction and I appreciate your efforts.
Yes - it does seem that everything on the net does seem to come from the TDC links. However I have sighted a recent post on another forum where Aussie Vets do recall seeing 8 Haflingers landing in the back of a Herc - I now wonder if what they saw was some Mules and the years have faded that memory to be Haffies.
Also taken from another forum - an abstract from an evalution of the Haflinger compared to the Mule

Abstract : Test experience with the Haflinger generally parallels that previously encountered with other foreign vehicles. From a performance standpoint, the vehicles are equal to and, in some areas, exceed comparable US vehicles. From the standpoint of the durability and reliability required of utility vehicles they are unacceptable. It must also be recognized that their use would mean the addition of nonstandard parts, special tools, and much more comprehensive maintenance publications then are normally available. The principal advantages of the Haflinger over the M274 lie in its easier handling, smoother ride, and slightly greater speed. These features are achieved at the cost of a heavier, more sophisticated vehicle. It is questionable whether such design features would be justified in an austere, special-purpose vehicle such as the M274. (Author)
