Kodak Carousel 4600 35mm slide projector w/ Ektanar C 102mm f2.8 lens (serial 21513219)

Note: One of the pictures shows the projector with a Carousel tray. By default the projector comes with no slide tray but 80 or 140 types are available as add-ons.  

This is a solid and reliable 35mm slide projector. It is fully compatible with Kodak Carousel slide projector trays and lenses. The 4600 is part of the third generation (made from 1981 to 2004) of North American Kodak Carousel projectors. The Carousel 4600 features an 'auto-focus' feature which, in projector speak, means that it adjusts the focus based on the thickness of the slide mount; this is handy for people with many different types of slide mounts in their collection.
