John Alfred Prestwich proposait en 1898 neuf différents modèles de cinématographes et projecteurs. Celui-ci est particulièrement rare.
"Model 3 Projector : the film being intermittently actuated by a dog-motion. This machine is fitted with automatic feed and take-up attachments, the spools being capable of accommodating up to 2000 feet of film. Two simpler patterns are constructed, but all have a removable shutter and interchangeable sprockets, which may be rapidly adjusted in order to pass a film of any gauge through the machine without possibility of damage. As many films of apparent Edison perforation are found, when tested, to be out by anything between 1/64 to 1/16 inch in the space of four pictures, this detail is of considerable importance. The simpler forms of camera are provided with focal-plane shutters, intermittent motion being secured by an epicyclic sprocket" (Henry Hopwood, Living pictures, their history, photo-production and practical working, London, The Optician & Photographic Trades review, 1899, p. 168-169).
