GAF Pana-Vue Automatic rewind knob with good light seals andThe GAF Pana Vue Automatic is an illuminated viewer that can take a stack of 35mm slides and cycle them through for quick viewing. The feeder is manually operated no motor here but it does make viewing a lot of slides pretty quick and easy. In good working order. The optics and backlight have some dust on them, which is slightly annoying but doesn't affect function. Runs on a pair of D batteries (not included) or with the AC adapter (yes included.)
