Trying to find out information on the set of Lamps. What are they made of? What Year are they from? What is the current Value?  I recieved them from a friend that did not know much about them. They look like brass but not really sure what that part of lamp is made of. There is a glass part and there is two light parts. It lights in the glass part with a small bulb and the on top with a reg 60 watt bulb. I am hoping that some one could give me some information on the lamp set.
