Suzuki M-20 10-hole diatonic harmonica in C key, made in Japan. - Model: M-20 - Brand: Suzuki - Key: C - Number of Holes: 10 holes - Country of Manufacture: Japan Thank you for looking. I purchased this at Taniguchi Gakki. I used it with a harmonica holder, so there are some minor scratches on the cover, but the reeds are clean and the pitch is good.
