      The Duo Six-20 got its name from the fact that it produced 16 half-frame 4.5x6cm (1 7/8" x 2 1/4") negatives on a roll of 620 film. A rangefinder was added in 1939.

      The Duo Six-20 was manufactured by Kodak AG in Stuttgart, and shares quite a few design similarities with the pre-war Retina I 35mm cameras. World War II caused the production facility to be shifted to making armament and ammunition components, ending the Duo Six-20 line.
