Apparently the actual oil burner was replaced somewhere along the line. The burner it has now is marked "The Rochester", and it has been modified to allow an electric bulb.
The lamp currently is set up to use one electric bulb. In my opinion the lamp would look even better with one or even two small bulbs in the base, to light up the smaller glass panels, and a larger bulb under the shade. The glass is in very good condition. The glass panels in the shade are easy to remove for cleaning.
Most of the items I sell come from estate sales and have imperfections. I try to describe all flaws in my listing and take lots of photographs to help you see the condition.
