This Braun Braun Nizo movie editor/viewer projects your film frames onto a 100 x 75 mm illuminated ground glass screen at any desired speed because it is manually controlled. Behind the screen there is a complete optical system with a 16 mm lens, twin lens condenser and silvered mirrors. Can be operated with 220V only, certain countries will need an additional step-down voltage converter.

Replacement bulbs are widely available. These are 6V 10W G4 type bulbs which can be purchased from here.
