Towards the end of 1961 Bedford introduced the VAS chassis and Duple produced a completely new design - the Bella Vista - for it. That year the maximum permitted length for coaches was increased to 36 ft and the maximum width to 8 ft 2½ ins, and Duple (Northern) designed and produced the Continental, with seats for up to 51 passengers. At the same time the Bedford Super Vega was replaced by the Bella Vega, using similar styling to the Bella Vista, and when Bedford announced the six-wheeled VAL in 1962, Duple introduced the Vega Major. For 1964, Duple introduced the Commander, initially built at Hendon but switched to Blackpool later, and in 1966 the Viceroy range replaced the Bella series on most Bedford or Ford chassis.
