DescriptionThe projector consists of a lamp housing equipped with a GE bulb, bellows that move on two telescoping rods for focusing purposes, a projection lens, all of which supported by a rectangular base. The projector can be tilted up and down. The slide holder can be removed. It is held in place with a thumb screw. The power cord seen in the picture powers both the projector and the fan fixed on the outside of the lamp housing, apparently designed to cool down the slide. It was most likely added later, so is not original to this instrument.
