antique chandelier

when we bought our 1929 ranch home this chandelier was hanging in the dining room. we recently purchased a new one for better lighting and kept the old one. was interrested in any information you could give me on this item. and its value please. could not find any markings on the chandelier itself just on the bar that connects to it. markings were B.B.Co 6157 APPLD FOR. but found nothing else on the chandelier itself.
