Vintage UFO pendant light with crystal glass

Vintage space age style pendant light with crystal glass shade. The bottom plate is made of very thick glass. The transparent parts on the side are made of plastic and the metal frame is made of aluminum. The lamp requires a standard E27/26 bulb. [Condition] Good. The lamp is still in very good condition. Three of the small plastic pieces on the side no longer have springs to hold them in place, see the last photo. If the lamp is moved, they may fall out or become detached.
