Here is a vintage hanging lamp or chandelier bobeche'. It has hangers for 12 prisms. It measures 4" across and has a 7/8" ID.
I purchased a partial estate LOADED with oil and gas lamps, shades, burners, flame spreaders, chimneys, sconces, tanks, and literally thousands of parts, which I will be listing over the next couple weeks so be sure to check out my store and add to favorites.
