The KW cameras were produced between 1919 and 1938 by KW,
Kamera Werkstätten Guthe & Thorsch, a German manufacturer, founded by Paul Guthe and Benno Thorsch, situated in Niedersedlitz, a suburb of Dresden. The Patent Etui cameras were introduced in 1920 and produced until 1938. Their extremely slim case - or Etui -  was slim enough to be slipped into a pocket.They were made in 2 formats, 6.5x9 and 9x12. As both factory owners were jews, they sold the factory in 1938 to Charles A. Noble, a Detroit camera maker, in a swap deal against his Detroit camera factory. Noble changed the production lines to 35mm cameras, the new Kamera-Werkstätten Charles A. Noble are mostly known for the Praktiflex, a 35mm SLR, already developed under the guidance of Benno Thorsch, which after the war became the famous Praktica.

Everything folds neatly into the housing. Do not forget to push the bed advance knob back before closing.

The camera opens via a button on the top. Lower the bed until it clicks into place. Extend, there is an automatic stop. You can either use the finder and the distance indications or a ground glass to focus. Set shutter speed and aperture, cock the shutter. Put a film holder into place, lift the dark slide and take your photo. Do not forget to put the dark slide again. To shut the camera, push the front standard to the end of the bed, press the hinges of the bed and it will close.

These cameras are about a century old. The lenses are uncoated and the shutters are simple. Nevertheless they are still nice cameras. 9x12 film is still made. Most of these cameras are very cheap, the 9x12 Patent Etui are rare, so they are a bit more expensive. They are simple to use and can give a lot of fun.
