Zeiss Ikon Kolibri

The Kolibri 523/18[1] was made by Zeiss Ikon in Germany, c.1930-1932 and marketed until c.1935. It takes sixteen 3x4cm exposures on 127 film. The camera has a collapsible lens tube and is arranged in a vertical style (to take a horizontal picture), with a flip-up viewfinder on the top. On the right-hand side are the winding knob and a tripod bush. The lens has small "feet" on one side, so the camera would stand horizontally, and a strut can be fixed below the lens to balance the camera verticall
