Antique 24 Panel Slag Glass Lamp Shade on Pittsburgh Lamp Base PG 45

Very good condition original Pittsburgh lamp base with a period 24 panel slag glass lamp shade. This was originally a gas lamp and converted to electric. It has been rewired and there is no damage or repair. The base is copper in a nice minimalist Arts and Crafts Craftsman style. Measures 20 1/2" high and the shade is a 15" diameter shade.
