The table below shows buses built from the AEC Regent Mark III chassis, with Weymann lowbridge bodywork (L27/26R), from 1950 onwards.
There were also some further buses built in 1954 and 1956 which are not included, but these had full width fronts (enclosed bonnets) and more seats upstairs.
Note: Ranges are used below; for example in the first row, ONU 630-639 indicates 10 registration numbers ONU 631, ONU 632 etc. to ONU 639. However, the order each bus would take numbers within ranges is not necessarily sequential.
