Images from The Alan G. Bates Harmonica Collection "Trumpet Organ" Harmonica by Andreas Koch, ca. 1910 NMM 8748. "Trumpet Organ" harmonica by Andreas Koch, Trossingen, Germany, ca. 1910. Koch vied with Hohner in the production of novelty harmonicas. This "horned" model was designed to compete with Hohner's extremely popular "Trumpet Call." It features a slightly more complex arrangement of the five horns than is found on Hohner's model. Ironically, the five horns are merely a facade, having no function other than being decorative.
