Former square ceiling metal silver crossfire

Great ceiling light glass chiseled (despite the weight I can say that it is crystal) and frieze of medallions and silver metal acanthus leaves. The ceiling date from before the 1950s, the rings of the casings are made of porcelain. The overhead is in very good condition, barely a few traces of oxidation on the silver metal. Two lamps for bulbs to screw gray cutot. I trying to better describe the characteristics (negative or positive) of this object, however do not hesitate to contact me if you want any other details or photos I could omit; I am happy to respond as soon as possible.
