Antique Slide Viewer with Hand Painted Glass Slides. It is made of tin. It is marked JAPAN Nippon Registry 152003 on a chrome plate. We have included a fresh bulb. It works with two D batteries. There is a small lever on the front that looks like it was partially broken off. This likely operated the swtich. We can get the bulb to light by pressing between the batteries from underneath. You could get the light to stay on simply by bending the copper to touch the bulb.
