Notes and Comments
The S211/221 was the first sound projector manufactured by Paillard-Bolex. The S211 model was designed as a playback-only projector for 16mm silent or optical sound film. The detachable lid contained a 15 Watt 8" speaker.
For sound projection in larger rooms, an additional 12", 15 Watt speaker cabinet was available as an accessory. It was supplied with a sound control box and 50' cord on a supply reel. The control box allowed both 12" and 8" speakers to be used simultaneously, and the volume of each to be adjusted individually. The sides of the unit could be folded down to form a support stand.
The projector was supplied with a 2000 ft aluminum reel and a 50mm lens. 35mm and 70mm lenses could also be purchased.
Serial Numbers and Dates of Manufacture
Although it was advertised in 1960, the S211 doesn't appear to have gone into production until 1961 -- a year later than the S221. The serial number on S211 projectors can be used to determine the year in which it was manufactured, beginning with 111801.  The table below lists the range of serial numbers allocated to the production run of the S211/S221 series.
