 The Filmo camera series started with the 1923 Filmo 70, beginning a series of models built on the same basic body that was to be continued for more than half a century.It was based on Bell & Howell's brilliantly designed 1917 prototype for a 17.5mm camera intended for amateur use.When invited (along with Victor) into Kodak's 16mm plans in 1920, the company was quick to see the advantages and immediately set about redesigning the 17.5mm camera for 16mm film.
