This 2002 picture of a 1995 Volgren bodied Mercedes O400, 42 (4020AO), on the Melbourne Staff Shuttle dates back to the times of the Nixon Group. The following year Dysons acquired the Nixon group which brought with it the Cobb and franchised APT operations including bases in Darwin and Alice Springs. This Mercedes, became 197 in the Dyson fleet.
In August 2004 42 is seen again as Dyson's 197. it has since be sold to Glenorie in Sydney and from there to Rover in Cessnock.
