(1958, The Bowery Boys)

This was the last of 48 'Bowery Boys' comedies. The plot concerns a poodle and trans Atlantic diamond smugglers, hence the stock shots from New York and London of mixed age.

The London scenes include RT family buses including the standard view of Piccadilly Circus, also the equally standard shot of trams on Westminster bridge:

Interestingly this much older footage features three AEC Ks and (as the shot fades out) an LT class AEC Renown at Westminster Abbey:
