Norfolk of Nayland's BDJ70, an ex-St. Helens RT type AEC Regent III with Park Royal H30/26R body, new in 1950 and withdrawn by them in 1962.
Alongside are two more Norfolk's single deckers, Dennis CGV70 on the left - click here for a better picture of CGV70 - and Bedford ACF181 on the right. Sandwiched between is another Bedford, HAY250, owned by R.W.Hooks, who operated a small coach fleet under the name Harwich & District Coach services.
Has anyone got any more details on these buses ?
