The Ica Icarette 6x6 roll film "No.495" camera was introduced in 1912 and discontinued in 1926 when Ica merged with Goerz, Ernemann and Contessa-Nettel in 1926 to form Zeiss Ikon. The camera uses 120 films (some early versions for 117 roll film) for 6x6cm exposures (and 4.5x6cm on plates). It is a horizontal style folding billows camera also known as "Model A", "Icarette B", "Icarette", "Icarette I", "No.493" (roll film only), "No.495" (roll film only), and "No.496" (roll film + plates). The Icarette series of cameras are non-self-erecting. After the incorporation of ICA into Zeiss Ikon, the camera series was continued under the Zeiss Ikon name but keeping the former ICA product codes. In 1930 the cameras were given new Zeiss Ikon product numbers. They were discontinued around 1934. The camera has a Novar Anastigmat 1:6.8 F=7,5cm lens, Collapsible brilliant finder, some versions have Iconometer (wire finder), focusing Lever on the bed, 3/8 inch 16 thread tripod socket, and a screw in shutter release plunger socket. The years produced were Icarette I (495), Icarette A (US catalogs), or Ica Icarette I (495) (1912-1925), Zeiss Ikon Icarette 493 (1928-1929), and the Zeiss Ikon Icarette 509/16 (1930-c.1934). The camera also has a pull-out tab in the back cover. In one tab position, the red window is uncovered for checking film advance, in another position the tab served as eyesight for the wire finder. The back of the Icarette is easily removed by pressing two little buttons at once on the top and bottom of the one side. When retracting the lens assembly and closing the bed, the brilliant finder collapses automatically to fit in the closed body. The camera has a sturdy metal construction, covered with fine-grained leatherette. Many lenses were fitted to the camera including the one mentioned above was the Baldour 75mm ƒ/8, Helios 75mm ƒ/8, Hekla 75mm ƒ/6.8, Maximar 75mm ƒ/6.8, Icar 75mm ƒ/6.3, Dominar 75mm ƒ/4.5, and the Tessar 75mm ƒ/6.3 or ƒ/4.5. Along with the lenses were a few shutters like the Ica Automat mod. X (1/25-1/100), Derval (1/25-1/100), Compound (1 second -1/250), and the Compur (1 second -1/250) When Zeiss Ikon was formed (1926).
