Antique Bent Slag Glass 8-Panel Hanging Tulip Lamp 11 x 10.5

Antique Bent Slag Glass 8-Panel Hanging Tulip Lamp 11″ x 10.5″. Not positive if that is what this light is called? It does have some paint, dirt and wear. Also, it is missing two of the bronze strips that coves where glass panels come together. Again, please see pics for best description.
