Designed by the film pioneer, Birt Acres (1854-1918), this was the first piece of film-making apparatus intended for amateur use. It used 17.5mm film, which was produced by slitting standard 35mm film in half. It is shown here with its carrying case, which was designed so that the camera could be operated secretly while still inside the case.
