Opaline suspension with porcelain counterweight circa 1920s-Energy saving-Monte and down retailer

Superb French rise and fall around 1920.
Good vintage condition.
The most economical of lamps because you adjust the height of the opaline with a simple gesture thanks to the counterweight.
You lower it to read or knit in your armchair. In medium position above the retailer table for the meal etc.
The shadow light puts you in a bubble of light, the rest of the room in a slight darkness.
An intimate and relaxing scene.
The lamp of happiness.

All the pieces are period and authentic, both the brass claw and the counterweight and the porcelain rosette.
The components of the article that I propose are on the enlarged photos 3,4,5,6.
Opaline is 25 cm in diameter. It is in perfect condition.

Only the wire, 150 cm long, is new to allow you an immediate installation.
Sold without bulb.
