Opaline glass wall lamp

What an original shape this wall light has! This is the first time I've come across one with a mushroom head-shaped lampshade. In addition, it has a completely porcelain fixing system that you don't see very often anymore. It must date from the beginning of the 20th century. It is made up of three pieces, one (the wall light) that is screwed to the ceiling or wall, through which you "pass" the socket, which itself is held in place by a small porcelain piece that is screwed onto the wall light, then the lampshade which is also screwed onto the wall light. The bayonet socket will be supplied with it but the wiring will have to be replaced. The small porcelain piece was broken in two, I glued it back on, it is functional again despite the small missing chip. The wall light is stained but it is barely visible once the lampshade is in place. The lampshade has a few small stains or marks that are not very visible. The lampshade measures 17cm in largest diameter, approximately 13cm in depth and 14.5cm in depth with the wall light system.
