A Duffner & Kimberly leaded glass table lamp, Pre-1920.

From an Ebay auction by Howard Booher.

This is a rare, early open top example. It has 4 heavy cast arms that are leaded in to the shade. These extend out to a solid ring that then sets over the top of the base for a perfect fit. 2 versions of this shade are pictured in an original Duffner & Kimberly catalog. The base retains it's original brown patina and 3 original Bryant sockets with acorn pull chains. The heat cap and finial are also original. The lamp is untouched. The shade measures 18" in diameter and stands 24" tall.
