The Arti-Six is a British Bakelite viewfinder camera made around 1950. It had a screw-tube lens - when taking a photograph, the lens is screwed forward, rotating on a helical screw thread and clicking into position; the tube is screwed back into the body for transport & storage. Controls around the lens give three speeds, 1/25-1/100, and three apertures (f/9, f/12½ and f18), and the option of time exposures. The lens barrel screw has three click stops, giving focusing for portraits (4-6ft), groups (6-12ft) and landscapes (∞). The back is removable for film loading, and simply clips into place. The base is plain except for a tripod bush. The film plane is slightly curved, reflected by a step either side of the back.
The Grand Manitou is a similar, French-labelled camera; both were made by a company called Artima. The Arti-Six bears a striking resemblance to the Wembley Sports Camera; the Wembley differs in having a larger advance knob, a metal plate fitted around the lens and around the lens barrel, and having a slightly slower (f/11) lens.
