Harvard lamp burner, as shown with gallery. 2 size burner, ready for wick and oil. This can be used on many lamps, and the addition of a flame spreader will give you a fairly bright light.
I will leave whether you polish it or not to the next owner. This is an antique, and do not look they just left the store! If you have any questions, please write to me and I will try to answer them as soon as possible.Thank you for visiting my listing!
