Beautiful Sankyo Silversonic 301 flute. Solid silver head, body & foot. This model has the factory E system, where the left side G cup is reduced from 17.5mm to 12mm to give an easier High E, as with the well known split E system. This system requires less maintenance and servicing.  Open hole version, in beautiful condition. Serviced by Sankyo technicians over in Japan before being sent to use, rechecked in the UK, then put up for sale.
