I have a table lamp with what appears to be made out of bronze;it is heavy. It has four bronze cherubs sitting on a black marble base. Going up to the finial are four ram heads. I have read up the correlation of the rams and cherubs, and it appears to be a biblical reference , with different interpretations. There is no makers mark, that I see. Also the power cord has an old two prong plug. Does anyone know about this item or about how much it would be worth? It is in great shape.
