Antique Bradley And Hubbard Leaded Slag Glass Lamp

I have an antique leaded slag glass lamp. It measures about 26 tall. The shade is about 21 across the widest point. It’s in very good condition as pictured. I see no damage except for a minor dent on the underside of a socket. There are no cracked glass sections. The base is very heavy. Made of a non-magnetic metal. This lamp could use further cleaning if desired.
