Rada Rollfilm-Kassette Film holder

No minimum price. Rada roll-film cassette holder, (film back) equipped with a dark sliding shutter, designed as an adapter for using 120/620 roll film for use with 9×12 plate cameras, which resulted in a 6×9 image or smaller with the two supplied masks in 6×6 or 4.5×6. That provided a significant saving in film costs. Moreover, one used the best smaller center of the optics. It replaced the glass plate or sheet film. Ingeniously, one could advance the film numbering via a small flap. It worked with all the major well-known brands from Agfa to Zeiss Ikon and the entire camera alphabet in between.
