YAMAHA M-15S harmonica, silver finish, with case. - Brand: YAMAHA - Color: Silver - Accessories: Case - Model Number: M-15S I believe this harmonica was used in school about 30 years ago... The case has been bleached and cleaned. The harmonica has been cleaned where possible. Since it is old, it is considered a junk item. It produces sound, but I cannot guarantee that all notes play or that the pitch is accurate. Please purchase if you understand that this is a used item. Thank you for looking.
