Rare television style slide projector with viewing screen. It's a slide projector that uses internal reflection to display the slides on an inbuilt viewing screen. It includes power cable and hard carry case I have just bought a new bulb for it and it's tested as working, the bulb & screen light up, it loads and unloads slides and advances to the next slide. It also includes a tape deck for audio presentation, not sure if this bit works, I haven't tested any of the audio functionality.
