The Rajar No. 6 folding camera was made by the British camera makers' group APM. Rajar Ltd. was part of that company. The No. 6 refers to Rajar's own film size. This camera was the first strut folder with all three main outer parts, the body, the back and the lens standard, made of bakelite. The camera was introduced in 1929. Beyond that fact it was a quite basic camera model, with meniscus lens behind an everset shutter that offers instant and time mode, film advance by key with help by a red exposure counter window in the back, and a reflecting type viewfinder. The finder as it is mounted above the lens opening behind a hole in the lens standard can be used for vertical exposures. For horizontal exposures the lever on which the finder is mounted can be swung out so that the finder is turned 90 degrees and positioned over the standard. The shutter release lever is placed below the lens standard. The camera was a strut folder with cross-swing struts. It made 8 6×9cm exposures on special Rajar film rolls for the square film drive of the camera.   There was also a series of Rajar No.6 box cameras.
