This is a great kerosene lamp in the Sheldon Swirl pattern with white opalescent font and clear base with a very nice brass burner and lovely glass chimney.  The lamp measures 6 3/4" in height to the top of the font and 14 1/2" in height if you include the chimney.  The brass burner is marked "Lincoln" on the thumb wheel.  The lamp is in excellent condition.  A wonderful antique lamp.
