Molded glass wall lamp or ceiling lamp

Pretty molded glass wall lamp of a slightly coppery, iridescent shade (in reality, a little less than in the photos). The pattern is a repetition of small pyramids that get bigger and bigger as you move away from the center. Originally, they were used as ceiling lights, but are so pretty that we like to highlight them by applying them on a wall, and why not to several! The glass globe is in perfect condition, the metal base has the marks of time and use: paint chips, scratches and various marks. The socket, in bakelite it seems to me, for bulb with large base (of 60w max according to the label still present inside) is at least to be rewired, or even to replace. The glass is held on the base thanks to 3 screws. This wall lamp measures 21 cm in diameter, about 10 cm in height and weighs 820g.
