The Roll Tengor is a range of folding-bed cameras made by Optische Anstalt C.P.Goerz AG. of Berlin from the early- to mid-1920s. The camera bodies are aluminium, with leather or leatherette covering. McKeown describes the Roll Tengor as a cheaper model of the Roll Tenax. It was made in several sizes: 4.5x6 cm (for 127 film), 6x9 cm (120 film) 6.5x11 cm (116 film), 8x10.5 cm and 8x14 cm. Plate adapters were available as accessories for all but the smallest camera.
The Roll Tengor was offered with several different Goerz lenses, including the f/9 Frontar, f/6.8 Tenaxiar and f/6.8 Kalostigmat. The shutter is either Goerz' own Automat three-speed everset shutter, a Pronto, or a Compur.
Most of the cameras have a brilliant finder, with attached bubble level, mounted centrally above the lens, as in the examples pictured here. McKeown shows the vest-pocket model with the finder mounted above and to the left of the lens.
