I've had this a few years. I would be interested to find out about it.its very ornate

It's very ornate with faces and columns around
The middle of the lamp. The base has four feet , and faces, and various carving effects. I don't think the white shade, and what holds it is original . I have no idea about it, I just loved it when I saw it. It's very dark through age. I think if polished it would come up a brassy colour. It's very heavy. If anyone can tell me anything about it , I would be very pleased.
