Omniplast Stereo Viewer
Germany, 1930s
The Omniplast company made several different black metal stereo viewers. Two were for 6 x 13 cm stereoviews: one with focusing capability and one without (pictured below). They also created a viewer for 9 x 12 cm stereoviews which looked like the Camerascope viewer. They also made cardboard stereo viewers.
Omniplast also made almost identical viewers that were branded for Awuco and Zeppelin.
