There were various attemps at a 17.5mm film gauge, but one was introduced by Pathé-Baby in France in the late 1920's with a projector and library of silent films. A 17.5mm camera was also advertised. Pathescope in the UK presumably imported some of these items but only appear to have advertised it once in their house magazine.
17.5mm optical sound-on-film was launched in 1933/4 with a sound system added to the silent projector. A smaller projector was provided for amateur use. By 1938 a larger machine appeared.
I have a very small collection of 17.5mm films and
equipment. I would be interested in purchasing other 17.5mm items
or a complete collection maybe. Contact me by E-Mail at:
