Argus C3

1930-1966 

Lens - Cintar 50mm f/3.5

This camera is commonly credited with popularizing 35mm film due to its being the biggest selling 35mm camera for 3 decades. Because of its shape it has the nickname "the brick". It has a viewfinder as well as a coupled rangefinder and it accepts interchangeable lenses.  My model is from the early 60's.
