6 Panel Antique Slag Glass Table Lamp Shade Art Nouveau Period

6 Panel Antique Slag Glass Table Lamp Shade – Art Nouveau Period 1920′s. Two pieces of the filigree metal overlay are off the shade on one panel. Another panel is missing one of the flowers/bell. The first photo shows the damaged filigree balanced in place and the second photo shows the pieces laying on the table below where it is supposed to go. The fourth photo shows the missing flower/bell and part of the vine missing in lower left corner of the panel (we do not have this missing piece). Diameter of shade is 16 inches with a height of 8 inches. We are hoping that someone has the ability to restore this beautiful shade.
