"A recent BBC drama about Churchill and his pre-war campaign against appeasement featured a number of AEC RTs disguised in pre-war London livery ." (thanks Chris Hough)
"Cobham's STL2377 was also present in this; it went for filming on a few different days, and each time had different adverts applied, which were stuck on with grease so as not to damage the paintwork." (thanks Nick Abbott)
Alan Sinclair notes "a prewar RT is seen crossing Westminster Bridge,I think".
