This is a vintage 1950s aluminum sick room vaporizer, complete with the original cloth wrapped cord. It is marked "Practical Elec Products Inc N.Y.C. Do Not Immerse in Water U.S. Pat. D 120371 115V 200W." This cute little vaporizer rolls on three small wheels on the base. It is in very good condition. Aluminum is a soft metal, and there are light scratches and a couple of minor dents. The handle and knob are black bakelite. MBR.
