Models I, I, III used 35mm film for 24x24mm exposures on standard 35mm film but in special Photavit cartridges. The film is pulled into the take up cartridge from the supply cartridge without the need to rewind. This also moves a cog that advances the film counter. Inside the cartridge is a standard 'Bolta' spool.
Standard model I of 1938 is black enamelled with leather covering.
Deluxe model I and all later models are chrome plated with leather covering.
