This studio camera was sold by the Belgian firm "Maison Naert". The workshop for the construction of these camera has not yet been determined.
Regarding this studio camera, the wheels are not all original and the foot stabilizer is missing. The photographic chamber goes up and down between the two columns by a system of two lead counterweights which each slide inside the columns. The load of the counterweights and the chamber are equalized which allows the raising and lowering of the chamber with one hand. Grundner's shutter is in the bellows, just behind the optics. It is a half-sphere which opens in two by the pressure of the air sent by the pear. An external accessory can block the air pressure to keep the hemisphere open while framing and focusing the subject. The firm Naert offered a Voigtlander Heliar lens with a 36 cm focal length. This camera having neither a mounting board nor an optic, I placed a Goerz Celor f1:5.5 36 cm on a 'home-made' board made of oak, like the rest of the camera. The builder's plate is a photo reproduction of an original.
The whole of this studio camera weighs 87 Kg
