Sky blue opaline blown glass lamp

Very beautiful lamp whose foot is made of sky blue opaline glass. It seems to me that it is blown glass because this foot does not have any "welding" that would testify to a molded glass. It probably dates from the 40s. All the elements seem original to me: the foot is surmounted by a bayonet socket in nicely patinated brass, bronze color, equipped with the ring that will hold the lampshade of your choice, an ovoid shape switch, silver plastic with pretty reflections, snake skin effect, and even the original socket (open at the back). It is so pretty that we can also consider not associating it with a lampshade but simply a beautiful "vintage" bulb. I tested it, it works, but the switch is quite "sensitive" that is to say that it is enough to press very lightly and the lamp turns on, even before having pushed it to the end of its ignition position. The glass is in perfect condition, the wiring seems to me in good condition. It measures 19 cm in height (socket included), 11 cm in diameter maximum. It weighs about 530 g.
