Rare, Lighted Table Top Stereo Viewer by Hugo DeWijs. Designed for 2 x 120 images but with care a pair of full-frame 35mm slides will fit. Inside is marked with maker's name and dated 1978. This is model number 37 and although many were coin operated and rented out to public places, this example is for 'free' operation. On operating the lever the next slide is bought into view and a fixed timer turns on the internal lamp. In full working order with a mixture of 35mm and medium format stereo slides.
