Images from The Alan G. Bates Harmonica Collection Rare Four-sided Mira Harmonica by Andreas Koch 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.
