Vintage Stiffel Style MCM Heavy Brass Hollywood Regency Ball Table Lamp

This is in very nice condition with very little wear.  It may be a 3-way light because the bulb didn't come on the first time I turned it, but came on the second time, and stayed on the third time going back off on the fourth time.  The total height is approx 25" with the arm.  Just to the socket is aprox 18.5".  It is unmarked, but has a distinct Stiffel style.  Weighs approx 6 lbs.
