We have several of the rotator lamps, Niagara Falls, a light house, a mill, a bus climbing a mountain, a cabin in the snow, the choo-choo and some others. They are difficult to find today. Also the plastic does deteriorate. The original ones were quite heavy and smaller. The outside was glass with the inside rotator made off celluloid. Here is a pot-bellied stove rotator lamp. Very appropriate for this thread, I think.....Helen
