Lamp, emerald green and gold ceramic base

Table lamp with a very pretty base in emerald green enamelled ceramic enhanced with gold edging. The aesthetics of the base with its shape reminiscent of a plant or a marine animal and these "typical" colours immediately remind me of verceram's production around the middle of the 20th century. But this lamp does not have a stamp. Its lines which hesitate between art nouveau and art deco seem to confirm this period. A surprising detail: the switch! I had never come across this model, it is the upper half which acts as a push button, it pivots to turn on or off. The electrical socket and the switch seem later to me, perhaps from the 70s. The brass socket, intended for a bayonet bulb, seems original to me. It includes the screw ring to hold the lampshade. I tested the lamp, it works. The ceramic base is in good condition, no cracks or chips. But some missing parts on the gold borders. Small marks on the metal ring that joins the ceramic base and the socket. As for the lampshade, it is usable but not in good condition: stains, marks and small dents, and the ring that hides the glue at the bottom is coming loose. Without any indication from you, this lampshade will be included in the package, but I can also keep it if you do not plan to use it (to give it to a lampshade friend). The base measures approximately 19 cm in height and approximately 24 cm with the socket. The base has a diameter of 8.8 cm. The central shape has a maximum width of approximately 11 cm and a maximum thickness of approximately 6 cm. The electric cable measures approximately 145 cm long.
