This unusual prototype shows the Contax Spezial . In a wider body , with the same mechanics of the current production Contax II, is built a fixed  Sonnar type lens  1.5 of 60 mm . No self timer. This special model was built in 1939 intended for the “Gestapo” forces in order to do pictures for  people reconaissance. This focal length was suitable to crisp pictures at  a distance. The high aperture lens turns the camera useful in any available ambient light. Observe; they were using “Eric Salomon picturing ways”, for their own intents.
