Stereoscope Planox

French table stereoscope in mahogany. Drawer of 20 glass plates of size 6 X 12,8 cm. The mechanism is to lower with the crank the plate that has just been viewed to put it in its place in the drawer and lift the next so that it is placed in the axis of vision. The lifting of the plates is done by a metal bar placed on each glass plate and which is taken by a magnetic arm. Fragile mechanism ....!
