Mid Century Italian Art Glass Table Lamps Unique Color

These are a unique shape and color that I’m sure are Italian and most likely Empoli.They look dark green in direct light and dark purple or gray bordering on black without direct lighting depending on the angle.I’m going to restore these with new acrylic bases and I wonder how these would look with 3 way switches with a light on the inside of the glass bodies.These have a double donut with striated columns going up to the bulb with a weight under each base.The wiring is really old which leads me to believe these are from the 1940’s or no later than the 1950’s.These going to get a tune-up and I’ll repost the restoration when there done.Thanks for looking.
