The Two NPIC Zapruder Film Events: Signposts Pointing to the Film's Alteration

[Phil Dragoo]

Perforated Number: The Zapruder 8mm film was identified during processing with a number 0183 perforated vertically within the 8mm width as a part of company practice for customer identification a control system to match the processing request or order to the film. The perforation would typically be located at the core of the returned 8mm reel, thus placing it following the scene exposed last the customer tails end of side two. Also note that as the laboratory receives the film, this location is at the outside end of the camera spool, immediately following the integral camera thread-up leader that will be removed prior to processing.
