Vintage Oil Lamp Etched Glass

I have up for bid a nice vintage oil lamp that has been converted to electric. The cord is not modern, so this must have been done some time ago. The lamp has a brass pedestal screwed into a square marble piece. The marble has some small edge chips. The glass is beautiful. It is etched with a wonderful design. I am not an expert in these thing but it looks like it could be converted back to oil. It is 13 inches tall. The marble is 4 inches square. Shipping will be 4 pounds priority from 04064. Thanks!
