Pair of vintage e-readers with articulated arms

Pair of 50s/60s e-readers. Diameter foot 20cm. Height "low": 120cm. Highest height: 153 cm. Length arm unfolded: 40cm. One of the bases is darker than the other and the "heads" on the arm joint are not exactly the same (see photos). They work very well, but I think it will be useful to redo the cord to bring the plugs up to current standards. Gilded bronze or brass, I don't know, each e-reader weighs 7 kilos. They are varnished. Their color is rather bronze.
