![]() ![]() This projector is a big one, probably used for external exhibitions. The source of light is provided by four lamps using mineral oil. A long
chimney (more than 50 centimeters) is providing fresh air to this aparatus.
The lens has a special slot for a pierced ring. This was used to adjust the aperture according to the luminosity wanted. The image focus can be adjusted by rotating a knob which is moving a rack-and-pinion gear linked to the lens.
