The original outline of the body for rear-engined double deckers was widely considered unsatisfactory and Sunderland Corporation took a heavily revised version on Daimler Fleetline from 1962-66 featuring a prominent peak at the front dome and a reverse rake to the upper-deck rear in the style of the contemporary Ford Anglia saloon car. Great Yarmouth Corporation instead specified double curvature windscreens of Alexander design on its Leyland Atlanteans (including a unique short-wheelbase batch in 1967) and on the last three Daimler Freeline single deckers. This then became a standard option at Roe who also optionally fitted the Alexander style double-curvature upper-deck front window on rear engined chassis, curving the line of the foremost upper deck side windows down to meet this, producing an elegant style which suited the Fleetline and the post 1964 low height Atlantean. Also in 1964 for that year's Commercial Motor show Roe built its first body to the 36 ft length permissible since 1961, it was an early Leyland Panther for the Kingston upon Hull Corporation Transport fleet. Unlike the Coronation trolleybuses they were to replace, the Hull Panthers were allowed to be one man operated. Roe then built versions of this body for Leeds on the similar AEC Swift from 1967 to 1972 and also built standee single decks on Daimler Roadliner and Fleetline for Darlington and on Seddon Pennine RU for Doncaster.
