Copal daylight Screen DS-2 for projector 1970 Germany

Very handy piece of equipment to be used with your vintage projector. You have a small foldable screen that can be used during daylight and looks like watching tv. You project the film into it and via the mirror it projects on the backside of a tv-like small screen. Called the Copal DS-2 Daylight screen and made in Germany around in the 1970’s. In great condition and ready to use (no power source needed) and even with instructions and in the original box (with some signs of storage and a little tape on top). Check out the attached youtube video on how to work this type of screen in practice.
