KODAK RETINA IIIC Type 021 I (1954-1957)
In the III series Kodak added a selenium exposure meter to the range finder. Both cameras I own differ only by the very different labeling around the rewind button.
Number 1: This camera has a film reminder on the rewind button for different proprietary film brands (Kodak TriX, Kodachrom, Ektachrom, etc.).
Number 2: On this camera the labeling lists general types of film in German (daylight, Tungsten, infrared, DIN gradings).
