Gaetano Sciolari Italian brass chandelier

I am looking to get a price on this antique piece that I recently acquired. I am unable to find another like it anywhere on the Internet even to get a ballpark of its value. This is a Sciolari six bulb brass / gold chandelier. Excellent beautiful condition a couple small spots of tarnishing barely visible. One picture is before I cleaned it up and shined it so it looks dirty but it gives you a better idea of the size as it’s being held in someone’s hand,. I’d say it’s about 20 pounds.

Good
