This is a Victorian era antique oil lamp. Burner marked R.E. & S. which is Everd & Co. Sussex England. I understand they were responsible for early wick patents. This is a double wick burner. The base measures 11" without the shade and 16" with. So the shade is a little over 6" and has a 3" fitter. The shade is pretty awesome. Etched floral cranberry to clear ruffled tulip shade. Absolutely beautiful. No chips or cracks. 
  I purchased a partial estate of a well known high end lighting collector. Everything from early oil, to gas, to early electric. The whole history. There are dozens of oil lamps and shades and THOUSANDS of parts, pieces and PRISMS. Apparently, her parents before her were also collectors. I am opening boxes and unwrapping items in newspaper and fruit tissue from the 40's. Tucked away all these years, not to be appreciated. I am not a collector. But I am very happy to return these fine items back into the hands of those that can appreciate them so much more. The craftsmanship of some of these items is amazing. You can't find that now.  
  I carefully package all items, and never ship lamps and shades together, unless small. If you have any questions, don't hesitate to contact me.
