Art deco lamp silver and opaline brass

Art deco lamp in silver brass and opaline lampshade. Work of the 30s. Nice overall condition. Remarkable patina. The height and orientation of the opaline shade are adjustable thanks to the screw and ball joint system to which it is attached. Note that the central rod is made of metal and not brass. The bakelite switch is original. On the other hand socket and electric wire are not original. The total height of the lamp is 48 cm. Its total width is 24 cm. The total diameter of the weighted base is 14 cm. The maximum width of the opaline shade is 10 cm (the few defects visible in places on the opaline are original. See photos and zoom). The lamp works with a bayonet bulb not supplied.
