Original early 1900's Bausch and Lomb Optical Rochester NY Model C Balopticon in the original case. These were basically early slide projectors. Serial number 19606. Looks to have all the parts, 4 lens, metal case and still lights up with an inside switch. Fairly large and quite heavy. Great display piece. Also comes with the wood slide holder and a box of old glass slides. This came out of a church so the slides are religious in nature. Good for someone who collects vintage audio/visual equipment. No major damage but it is likely 100 years old or close to that.
