Agfa Ventura 66 V Bellows
The camera is German made by the AGFA company of Munich, Germany. It is marked “MADE IN GERMANY, U.S. ZONE”. This dates the camera to the 1945 to 1950 time frame.
This would make the camera correct for an early BGS trooper to have been carrying it while touring around the base on the “Dienstrahd” bicycle. The U.S. Zone designation indicates the time period after WW2 when Germany was divided up into the different zones that were occupied by the various Allied military forces.
