This is a 1960’s era, black and white film made by the U.S. Air Force: The 16mm Motion Picture Projector. Care and Maintenance. The film was made to educate projectionists about the use of the AQ2A1 model 16mm projector, which is more commonly known as the JAN or Joint Army Navy Projector. These rugged projectors were designed to rigid U.S. government specifications and built by a variety of manufacturers including Bell & Howell and Federal. Their heavy, metal construction meant that they could supposedly survive a four foot vertical drop (such as might be encountered when a ship hit heavy weather or during transport to the front lines).
