This camera, which looks very much like a TLR, is called the Bolsey-Flex. It was produced in Germany in 1954. However, according to the available information, it does not seem to be a true TLR camera, yet it still uses 120 film to shoot in a 6x6 format. It features an 80/7.7 lens with three aperture settings: 7.7, 11, and 16. Additionally, it has a double exposure function. Most notably, it boasts a unique gray-green casing and a circular viewfinder on top.
