Adjustable suspension from the 70s/80s

Very nice suspension from the late 70s. Model called "go up and down" with lampshade equipped with a traction handle allowing height adjustment by the wire of the luminaire from 60 cm to 160 cm, very practical above a dining table for example. The lampshade is made of duck blue satin metal on the outside and white on the inside. Its diameter is 44 cm. The ceiling lamp is 9 cm in diameter and 10 cm high. In excellent condition, this beautiful luminaire will be ideal in a kitchen above a central island or a work table.
