The rear of the bus heading off on its two and a half hour tour.
 
The cab interior shows the Routemaster is RM1660 (660DYE) and this confirms with records. The bus was exported to New Zealand on withdrawal from London's Gillingham Street, Victoria depot way back in 1986, so had been Down Under for nearly 22 years.
