Swiss made 16mm non-sync camera. Very popular.

Bolex is a Swiss company that manufactures motion picture cameras and lenses, the most notable products of which are in the 16 mm and Super 16 mm formats. Bolex cameras were particularly important for early television news, nature films, documentaries and the avant garde, and are still favoured by many animators today. Whilst some later models are electrically powered, the majority of those manufactured since the 1930s use a spring-wound clockwork.
