Kodak Signet 80
The Kodak Signet 80 is an interchangeable lens 35 mm rangefinder camera produced from 1958 to 1962 by Kodak in the USA. The body, largely constructed of die-cast metal and Bakelite, has a coincident coupled rangefinder combined with a very nice life-sized projected frame viewfinder. The camera has a synchronized behind the lens leaf shutter with speeds from 1/4 - 1/250 sec. plus bulb.
