The Cewes is a strut-folding camera for both plates and roll film, first made in about 1902-3 by Körner und Mayer, the company which became Nettel Kamerawerk. It has the strut system which became characteristic of Nettel, using adjustable strut extension for focus control, with the end of one strut indicating the focus distance on a scale in a slot in the camera body.
McKeown lists the camera in several sizes: 6x9 cm, 9x9 cm, 9x12 cm and 10x12.5 cm.
Collection Appareils shows an example with a Nettel 140 mm f/8 Aristo Rapid Aplanat lens and a Bausch and Lomb pneumatic shutter. In this example, the lens standard is supported on a folding bed as well as by the struts. McKeown shows a catalogue illustration of a Cewes which has no bed, however. Both illustrations show a folding wire-frame finder, of the sort used on the Nettel and other later Nettel Camerawerk cameras.
