Vintage GAF Pana-Vue Automatic 2 x 2 Slide Viewer with built-in battery recharger. Recharges "D" batteries when used with transformer. Wide screen viewing of all your slides in 2x2 mounts. The unit itself has some minor marks (see photo). Comes with proper cords, batteries not included.
We have not tested it, but appears to be in working condition. Great for collectors or hobbyists.
