Sciolari style chandelier from the 60s

1960s mid-century Italian Sciolari style chandelier with 6 lights, natural anodized aluminum structure, hand-blown Murano glass spheres. The original escutcheons are in bakelite, and the replaced ones are in plastic. The chandelier has been designed for double switching.
The chandelier has the following defects; one sphere has a broken hole in the glass, visible in the photo, which does not affect its functionality. The aluminum frame has lightening of the metal. The low end of 3 lights doesn't work. Some trims (4) have been replaced (they are not original).
Once repaired it is a true masterpiece.
