Dating back to the early 70s, this projector operates on HP11 batteries (now known as LR14, R14RZ, MN1400 or MX1400, 14A and 14AC) and a small light bulb. Still boxed, including the instructions which are wonderfully dated - "Ask Mummy or Daddy if they've got any slides - perhaps you'll be able to show your friends what a fabulous holiday you've had!" Also included are nine strips of cartoon slides to colour in and one pre-printed strip of slides. Does not look as though it's ever been taken out of the box, although one of the "special coloured pencils" is missing. Box is in excellent condition too.
