1960s articulated desk or workshop lamp in cast iron and metal

Beautiful desk or workshop lamp probably dating from the 1960s-70s. The base is made of cast steel, the rest is metal. The red lampshade is adjustable. Signs of use, especially on the lampshade. I preferred to leave it as found, which gives it a certain industrial charm. The electrification has been redone at some point and has been checked. E14 socket. This is the first time I have seen a lamp with such a cast base (finished in satin black). Thanks (or due) to the base, the lamp weighs over 1.5 kilos... Clean and ready for use.
