1949 Casca II
.
.The Casca II was the most sophisticated interchangeable lens
rangefinder camera of its time. Innovative design features such as
bayonet mounted lenses, projected brightlines in the viewfinder for 85
and 135mm lenses and a flip up back for easy film loading were way
ahead of the competition; Leica would have to wait until 1954 before
offering similar features on their M3. Shutter speeds were
selected by a sliding bar on the back of the camera. Sadly, after
making a few hundred cameras production was discontinued after Leica
threatened to sue over patent infringements (shutter design).
