 DATE: Early in the film, the character of Bob Crane is seen playing  the drums in his house. On the underside of both cymbals the large  black Zildjian logo is clearly visible. This part of the film takes  place in 1964, but the Zildjian company did not put this large logo  on the underside of their cymbals until over a decade later. In 1964  they would only have had a manufacturers stamp on the top and no  ink logo. They are clearly modern cymbals.
