The composite body had been revised post-war, with a new patent waist rail, the teak structural member now covered by rolled steel plate. In 1957 the composite double decker reached its final form with teak framing to the lower deck ceiling or upper deck floor and an aluminium framework above. This was to continue in production, mainly on Daimler half-cab chassis until 1968, the last batch being built for Northampton Corporation on CVG6, replacing earlier Roe-bodied CVG6s which at the time comprised the entire Northampton fleet, all but five having composite bodies.
