Very handy slide viewer from Germany by Revue used for slides with x5 windows (so 6×6) slides. It comes with a trafo build in so it does not need power cells. It has a European power plug but when needed I can included a US plug changer. Still in the original box. It is checked and working. Some signs of use but no cracks or chips, straight from the 1980’s. Box measures 17 cm or 7 inches high. Check the video for the real manly way to few your old slides.
