Set of three vintage 60/70 ceiling lights

These ceiling lights were in my grandfather's garage. He tinkered and had many spare parts to repair lighting fixtures. The glasses date from the 60s/70s, they are very fashionable currently, in amber glass, they are in excellent condition. The lot includes 3 glasses and their supports. They are sold alone at 30 euros each or 40 euros each with the supports. The diameter of the glasses alone is 21 cm with a height of 10 cm. The diameter of the complete ceiling light is 30 cm.
