This is D. I have confirmed that it produces sound. It is used, but has been cleaned before listing. It has been disinfected with alcohol. I bought it a few years ago, but quit soon after, so I believe there is little sign of use. Please refrain from purchasing if you are sensitive. This is a Hohner Blues Harp, a 10-hole blues harp in a silver and brown combination. - Brand: Hohner - Model Name: Blues Harp - Color: Silver/Brown - Material: Metal/Wood - Range: 10 holes Thank you for looking.
