Molded glass wall or ceiling lamp

Charming wall lamp or ceiling light in molded glass, round in shape, with a décor of pyramids organized around a central spiral. I see it well on a wall, accompanied by several others, a little like the accumulation of flat baskets. It is equipped with its metal base painted in white, pierced by several three holes to fix it to the wall (screws and pegs not included) and its plastic socket (for bulb with small cap, be careful the bulb must be quite small). It is to be rewired, and maybe change the socket that I have not tested. The glass part is fixed on the base by turning a third of a turn. The glass is intact, the base has some points of superficial rust. It measures 15 cm in diameter, for 6.5 cm in height (including the base). She weighs 660 g. Other sconces are available in my shop...
