Mira Harmonica by Andreas Koch, Trossingen, ca. 1920

NMM 7717. Mira harmonica by Andreas Koch, Trossingen, Germany, ca. 1920. In the 1920's, the Andreas Koch Company made many unusual harmonica models. Although four-sided harmonicas were common, this version, with the harmonicas mounted in a central horn-resonator, is unique as far as is known. The original cylindrical box makes it even more of a rarity. Alan G. Bates Collection, 2000.
