Pair of industrial lamps

Pair of vintage industrial articulated lamps. They can also be called architects' lamps. They are white, with a vice fixing. The switch is on the back of the head. The head is quite original, the length is 22cm and its opening diameter is 13cm. One lamp has a 60cm cable, the other 120cm. Height of the lamp: 112cm fairly good general condition. A few brands that give them character. A slight dent on one of the two heads. Bayonet bulb for one and screw base for the other.
