THIS A CENTURY 70MM SOUNDHEAD MODEL R31-E. SERIAL NUMBER IS 819.
Century Projectors are world-renowned for quality and reliability. Developed as an offshoot of Simplex designs, Century came into its own in 1939 with the Model "P", soon followed by the Century "C" Projector in the early 1940s.
Century was an innovative company, designing and building several different versions of the "C" projector, including the VistaVision and "DD Cinerama" (double-shutter, 5-perforation 35mm) machines in the 1950s.
These innovations led to the JJ 35/70 Projector in 1960.
Imitation is the most sincere form of flattery, and no other projector design has been so often copied.
Witness Cinemex (Mexico), Cinecita and Westar (USA -- Westrex and Westar were manufactured under a license granted by Century in 1950). All are direct copies of the famous Century design.
Ballantyne of Omaha / Strong International purchased the Cinema Products Division of Optical Radiation Corporation, which included the manufacturing rights of the Century Projector, in 1993.
Simplicity in design, quality workmanship and unexcelled performance are hallmarks of the Century Projector.
The mechanism is easy to both maintain and service. With a heritage dating back more than sixty years, Century takes its place as one of the most popular film projectors ever used in the Cinema Industry -- the Standard by which all other motion picture projectors are measured.
