My copy of the Shirley Wellard came with the original case and instructions leaflet.The screw at the bottom of the film cassette can be used to adjust its fit in the camera film chamber.The top cap of the film cassette can be removed by unscrewing.The window is opened after the film is fitted into the camera and the back closed in order for the film to advance freely.The top cap of the film cassette can be removed to access the spool.The film cassette is made up a metal case, with a revolving window, a spool, and the screwing top cap.After the film is loaded in darkness, the window of the cassette is closed (in darkness).Bottom view of the Shirley Wellard loaded with film. With the window closed, the cassette can be manipulated in daylight.During loading, the window of the Shirley Wellard is kept shut. Once the back of the camera is closed, the window can be rotated to the open position.The rewind handle sits proud when a Shirley Wellard cassette is loaded.
