1901 Edison-Bell Duplex Concert Edison-Bell initially purchased Edison Concert (Banner) machines, converting them to play both standard and Concert sized cylinders. By 1903 Edison demanded that Edison-Bell no longer sell his products thus forcing the company to produce their own product. Offered only in Europe and having sold few, Edison-Bell Duplex Concerts are rare on both sides of the pond.
