Nickel Plated Brass Kappa Ceiling Lamp by Sergio Mazza for Artemide, 1960s

This large pendant was designed in the 1960s by Sergio Mazza for Artemide.
It is made from a nickel-plated brass structure with an opaline sandblasted shade and a molded clear glass shade. Its electrical system features 4 light holders (E27/large incandescent bulb) as showed in picture. The lamp remains in overall good vintage condition: normal oxidation patina wear consistent with age and use. The internal metal structure has been repainted. I have official proof of authenticity such as vintage catalogs,
designer records,
or other literature sources and take full responsibility for any authenticity issues arising
