Industrial lamp with articulated arm and clamp at the base produced by the historic company "A. Perazzone To." The lamp is completely made of steel with an articulated and rotatable head in nickel-plated brass. The arm is made of metal mesh with a "caterpillar" structure, which means it can be completely orientated and tilted in any direction. The original switch is characteristic. The bulb holder is original. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution, European Plug (up to 250V).The wiring of this item may be original and might need replacement, if not specified otherwise.
