Grand Shinano Concert guitar, model GR-150 in very good cosmetic and playing condition. Serial number , made in Japan. Spruce top, mahogany back and sides, rosewood fingerboard.  Has some minor dings and scratches but no cracks.  There are small hole markers on the fingerboard and sides that are probably not original, otherwise the guitar plays wonderful.  Please review all photos as they are part of the description.  Check it out...thanks!
