70's glass ceiling

Large-scale ceiling (31 cm diameter) of opaline-type glass, petticoated at its base and bordered by a transparent feast. 180 cm of adjustable electrical cable (rare length but practical for high ceilings) The fixture is in good condition, only a few darker spots are present (but barely visible) I try to describe in all the best and honesty the peculiarities (negative or positive) of this object, however do not hesitate to contact me if you wish for further clarification or photos that I could have oised; I would be happy to respond as soon as possible. Ref 13/20.
