For collectors and enthusiasts of vintage cinema gear, the is a fascinating piece of mid-1950s engineering. As a 16mm sound projector, it was designed for institutional and educational use, and its feature set was remarkably advanced for its time.

The 622’s standout innovation was its “jewelled” film transport. Bell & Howell incorporated sapphire inserts in the gate and intermittent shuttle to drastically reduce wear, promising a longer life of faultless projection. Performance-wise, the projector was built to impress. It boasted a tremendous light output, thanks to an aspheric condenser and a high-efficiency lamp that delivered over 80% more brightness than earlier systems. Sound reproduction was equally robust, with a precision-balanced flywheel to eliminate wow and flutter, and a germanium photo-diode for stable, low-noise audio.

However, perspective is key. This is a machine from a different era. It is heavy, requires regular maintenance (like belt replacement and lubrication), and its vacuum-tube amplifier can be finicky by modern standards. The 622 is not a plug-and-play device for casual viewing; it is a labor of love for the tinkerer.

Verdict: The Filmosound 622 is a beautifully built workhorse that represents the zenith of 1950s 16mm projection. For the vintage film enthusiast willing to invest time in upkeep, it offers an authentic and rewarding cinematic experience.
