This black, tin Fitaksop 0 is also designed for miniature 30x70mm views. The design is the same as the NPG tin advertising viewers. Around 1920, NPG sold its stereoscopy assets — views and viewers — to Bing-Werke who continued producing the miniature folding stereoscope in all black.

Fitaskop 0 - Glossy Black (NPG Style)

The label inside the box top promises “magnificent, three-dimensional effect, just like with the large apparatuses.” It’s accompanied by 3 series of stereoviews of the Harz mountains, published by Carl Hildebrand.

Viewscope - Deluxe Fitaskop

The gold border, logo, and collapsible design of the super-glossy Viewscope stereo viewer are the same as Bing-Werke’s Fitaskop 1 viewer (not pictured); however, the Viewscope accommodates larger 45x107mm stereoviews. The Viewscope box has the same design as other Fitaskop boxes, except that the word “Viewscope” replaces the word “Fitaskop” and the “1c” is changed to “2c.” We aren’t sure what prompted the branding change to Viewscope.
