Mentor Klapp II
Mentor Klapp II 9 x 12

The Mentor Klapp II was made by Goltz & Breutmann – Fabrik Photographischer Apparate, name that later changed to Mentor-Kamerafabrik Goltz & Breutmann. It was introduced circa 1900 preceding most other makers in the klapp camera manufacture. It was made until the 1930s and was one of the most successful strut-folding cameras. It was sold rebranded by many other makers in Germany and France, with different types of lenses and for a variety of plate formats, often as the low cost strut-folding of their camera range.

This particular camera is from the Mentor factory and is for 9x12 cm plates. Its early design, especially the combination of cut-outs on the lens standard and focal plane shutter type, suggests fabrication date around 1905. It is a wooden camera covered with black grained leather, with single pleated dark leather bellows and four single-piece round struts. It has a folding Newton finder.

The focal plane shutter has separate controls for slit width (operated externally but requiring observing the slit internally) and spring tension, and delivers speeds from 1/6 to 1/1300 seconds. The spring tension is controlled by a knob on the lower shutter face with a nominal scale (1 to 6) on a wheel on the opposite camera side. The slit width is operated by pushing a stud on the upper left side and then rotating the knob on the upper right side, while observing the slit internally.

The wooden front standard has cut-outs for setting the camera and vertical and horizontal movements by rotating the lensboard, for perspective correction. The lens is a G. Rüdenberg Hannover Doppel-Anastigmat Geroplan of 13.5 cm of focal length and maximum aperture of 5.4. Focusing is made by a lever on the lens barrel.
