The Columbia BK was an entry level machine competing in price and style with the Edison Standard Phonograph. In 1907 Columbia had a flash of insight: if a back bracket and hollow tone arm could improve a disc machine, why not mount such an assembly on a cylinder Graphophone? A series of Columbia models including the BE, BF. BG and BK were retrofitted with the new apparatus adapted from the disc Graphophone, and the letter T was added to the model identification, probably standing for Tonearm.
