1937 Rolleiflex Automat was my Grandmother's camera that was purchased
in 1938 in Bogotá, Colombia from a refugee of Hitler's Germany.
This is
the first Automat model and has bayonet mounts for accessories on the
f3.5 / 75mm Zeiss Tessar lens in a Compur-Rapid shutter. This first
model has no sportsfinder and no ruby window. The automat name is due
to automatic film feed. It still works!
