Bankers Piano Table Lamp 1920s Solid Cast Metal Marked "H Pat Pend", Small 9 inch tall Pull String

This listing is for Bankers Piano Table Lamp 1920s Cast Metal Marked "H Pat Pend". This is a Small piece measuring only 8 5/8 inches tall. This works perfectly as pictured and takes 1 small light bulb- included, but unsure of how much life is left so a new one could be needed soon. I believe the body is Cast Iron ~ The entire piece strongly attracts a magnet. This stands 8 5/8 inches tall to the top of the attached Shade. The base measures 5 inches deep, 4 inches wide. The Head or Shade measures 6 1/4 inches long. This has a on/off Pull String hanging from the light socket inside the shade. The shade is set and does not change positions. This, electrically, works perfectly and is plug in electric. Great piece with no damage, corrosion, rust or other issues but it may need a good Cleaning to remove dust. I do not know the Maker or actual date this was made so I am guessing 1920s because of the Art Deco Pattern to the shade and Stair step base, the fact that this piece is all metal and the style of electric. See pics.
