Hohner Chromonica 270 Key of C - Brand: Hohner - Model Name: Chromonica 270 - Accessories: Case - Number of Holes: 12 Thank you for viewing. This is a chromatic harmonica by Hohner. It's an older model, but I've checked its functionality and cleaned it. About six months ago, my interest shifted to blues harmonica, and this one has been sitting unused since then.
