This is a slide projector, color CABIN III, and an AUTO CHANGER II. It's a slide projector for projecting 35mm slide films onto a screen, and an optional AUTO CHANGER for setting up many slides and manually advancing them one after another. They are old, but I think they have almost no scratches or stains because they were stored in a box. I have confirmed that the lamp lights up and can project slides. There are also instruction manuals for the projector and the auto changer. I will also include a 35mm film cutter as a bonus. I kept them thinking I might use them again someday, but I never did, so I've decided to sell them. Thank you for looking.
