The main material in this gorgeous chandelier for someone to complete an Art Deco look to a room is chrome with some copper, appears to be a machine stamped metal I’m not sure it is a rose gold color, a glass sphere in the center. But the original wiring I’m only guessing from the 20’s-40’s… It is 12” tall from base and 14” across… each of the arms with the bulb would go is 2” for a glass globe / shade to fit. I am not sure what the original globes would look like . This should definitely be re-wired for fire safety and polished. I apologize for not polishing but not sure what all the metals are and I don’t want to ruin this . Please feel free to ask for more info but I’m not comfortable taking it all apart.
