Antique Heavy Cast Iron Exterior Wall Sconce Purchased In Las Vegas, Nevada

This is a heavy Cast iron light fixture. I purchased this fixture in Las Vegas, Nevada. There is one wire going down the tube in the middle but apparently a full conversion has not been done. The best guess is this light could have hung on The Venetian or Caesar’s Palace to complement their Italian and Greco-Roman architecture. This is a great piece of Vegas history, I just don’t exactly know where it fits! The fixture measures: Backing Plate: 19” x 6”. Total Height: 30” Diameter of top: 10” Diameter of bottom: 6 1/2” Six Sided for six pieces of glass. The swing-out door located in the glass panel area functions fine and has a thumbscrew to keep it closed.
