Episode 4:
A brief appearance in this Cold War drama by preserved London Transport Green Line T499C (ELP223), a 1938 AEC Regal O662. Unusually this scene is both accurate AND an anachronism, since although the bus is historically correct, the fleetname of owners Ensign Bus and fact that the rear destination reads 'X55 Lakeside' are not! Lakeside Shopping Centre opened in 1990. (thanks Derek)
