Summary These trucks were built by International Harvester Co, at their Dandenong, Victoria, manufacturing plant. In its heyday two assembly lines worked in tandem, with Army vehicles occupying one line, and trucks for commercial use were produced on the other line. These vehicles, both 4 x 4 and 6 x 6 were designed by ADE and put through their paces at the Army Engineering testing ground at Monegeetta. The engine in these vehicles was available in the commercial vehicle, but only with a single carburettor. Also, the army design with approval, led IHC to developing their first cab-over truck in Australia, which was known as the AACO (Australian A Line Cab Over) series of vehicle, which was followed later by the ACCO (Aust C Line Cab Over).
