Crystal Chandelier, with 10 fixtures, weighs approx. 14 pounds, there is a tag on it that says Electric fixtures, Insp. E 28140, Underwriters laboratories Issue No. C. 40,528, the arms on the chandeleir does not have a seam in them, none of the glass on it has a seem. Trying to find out how much it is worth. Came out of a house that was built in the late 1940's or 1950's. Any help would be appreciated.
