This is for sale a Dukane Model 28A33 Film Strip viewer for 35mm film. It is a 1986 model. It is more or less a projector and works great for viewing 35mm slides. The lamp is in perfect condition and the projector itself is in good working condition. It does need to be cleaned out as it was sitting in the closet of a classroom for a couple years and is kind of dusty. I have no idea how much this is worth, so name me a price if you are interested.
