Vintage black Polish industrial pendant lamp

An old, polish industrial lamp from 60’s. Lamps of that type were commonly used in factories and workshops. The top part is made from a solid piece of cast iron. The glass element is authentic and intact. We thoroughly restored these piece and gave it a black enamel look. We installed an E27 socket, max 100W. The lamp comes with one meter of steel chain and black textile-coated cable.
