Chronology of cameras Bentzin
The Fokal-Primar is a strut folding camera that was produced by Curt Bentzin (Görlitz) between c. 1902 and c. 1938. It is a wooden camera covered with grainy black leather, with single pleat leather bellows, and this particular model was designed for 9 x 12 cm plates. It is clearly from the period before 1931, as the minimum shutter speed is 1/3 second, but probably much earlier due to the non-optical viewfinder, but with a small blue lens for B&W preview. The camera struts are articulated.
The focal plane shutter has separate controls for slit width (the larger upper knob) and spring tension (lower smaller knob with a small reference window). It delivers speeds in the range 1/3 to 1/1000 plus T.
The lens is a Clément Paris Anastigmat Texor of 135 mm of focal length and maximum aperture of 4.5. The front standard, pulled out by two metal holders, has horizontal and vertical movements for perspective correction.
