Rare 4 light cocoon pendant

This is a rare and beautiful vintage light fixture. It dates from the late 60's to mid 70's. The cocoon shades are rarely found in this 4 lights configuration. Additionally, each light is fully articulated. The cocoon shades move up and down, and their wooden support pivot 180 degrees. The overall diameter is 40cm. The minimum height including the cable is 70cm. The cable is extendable up to 165cm (ideal for high ceilings). The lamp is in excellent condition, considering its age...thank you.
