| 2451M was one of the second batch of Mercedes-Benz vehicles bought by London Transport, which comprised 10 curtain-sided 307D trucks for use by the advertising department. The lettering on the cabside reads Advertising on the Move, London Transport Advertising. Note that unlike most curtain-sided vehicles, the sides here appear to be open upwards. Photographed at Acton Vale on 2nd January 1988. |
