Antique vtg 23 LAMP BASE for Slag Glass Shade Pittsburgh/Miller Original Paint

Large 23 Tall Base for a Slag Glass Shade. The painted surface is original and in good shape with normal signs of age. The design and quality appear to be that of Pittsburgh or Miller Lamps, but it is not marked. The round platform bottom is heavy cast iron, and the stem is spelter, or a metal that does not take a magnet. The base is heavy and sturdy. The base is 23 tall. The bottom is 8-1/2 diameter. The old sockets are untested and there is no cord, so this will need to be rewired for use. It could also use a careful cleaning.
