Architect's lamp, articulated desk lamp in yellow lacquered metal

Pretty architect's lamp in yellow lacquered metal (between lemon yellow and pale yellow) with multiple joints to adapt to all uses: fixed to a desk, a workshop table or why not as a bedside or reading lamp at the end of the sofa. It is mainly made of metal (lampshade, arms, triangular plates at the joints, fixing support, springs) which suggests that it is more of a model from the 70s than the 80s, without certainty however. I cleaned it carefully and tested it: it works. It is intended for a large screw base bulb (E40). It is in good general condition, functional, lampshade not deformed, electrical system in good condition, but obviously it has some signs that testify to its age: small losses or scratches on the lacquered parts, a little superficial corrosion on the screw heads and perhaps there was originally a "flat head" on the screw of the support to tighten on the desk, this is not the case on all models but in any case, I can provide you with a small wooden plate to insert between the screw and the surface on which the lamp will be fixed to avoid marking it (please remind me when ordering). The lampshade has a diameter of 19 cm when opened, each arm measures approximately 38 to 40 cm.
