Vintage 1970s blue architect desk lamp

Hello, Antique articulated lamp from the 70s, completely redone and restored with respect for the object. Type BZ-18 lamp. The lamp is not signed or identified but is authentic from those years. All the elements have been painted and varnished properly following careful disassembly. The wiring, switch, plug and e27 socket are new. I have all the photos of the restoration and its original condition. The lamp is made of metal and PVC, in good condition with some marks of time (1 inch on the bowl, see photos) otherwise flat. The vice supplied with the lamp (the one in the photos) is not the original one, but a new adaptable part which fits perfectly. Dimensions 60cm high, depth 50cm and the diameter of the bowl is 17cm. The lamp is supplied without bulbs.
