A Pressure Slide was available in the 1930s that replaced the dark-slide to allow roll-films to be used with the plate back still in place.

This converts the Cartridge Kodak into a plate camera.

This fits a Contax model II or III allowing 3 x 4.5 cm plates or cut-film to be used. The plate was held in single metal slides having a spring that pushed the plate forward when the draw-slide was removed. The plate had the same register in the camera as 35 mm film.
