Holophane Dentist's Chandelier

Chandelier of the holophane brand in prismatic glass and white painted metal, circa 1920. Originally, this lamp was mounted on a telescopic and adjustable arm and was used for dental care. The size and use of this lamp have made it a difficult object to find in its complete version. It is equipped with a central rotary switch allowing one or two or three or four lights to be lit simultaneously. The sockets (b22) and the switch are original but all the wiring has been redone.
