Kricheldorff Folding-Strut Mirror Reflex Camera, c. 1895

Fritz Kricheldorff, Berlin. Flat design for plates of 9 x 12 cm, black effect paint, double Anastigmat 7.7/120 mm. According to Frerk: The first folding reflex in the world! Resembles a rollfilm camera, but only the strong shutter cloth is housed in the useful handles. To unfold the camera, what appears to be the frame viewfinder serves as a handle for pulling up the mirror mechanism. When the shutter button is pressed, the mirror folds up and the shutter is revealed, cloth is good, mirror probably replaced, bright focusing screen image for this light intensity, leather parts of the viewfinder damaged, at first glance there appears to be damage to the paintwork, but inspection reveals that the lacquer is simply designed to look this way. Focusing screen back replaced. – Extremely rare reflex camera! – Literature: Abring I, no. 579.
