NMM 8991.  Chromatic harmonica by M. Hohner, Trossingen, ca. 1910-1930. The chromatic harmonica was introduced in 1910 as the alternative to diatonic harmonicas. The chromatic harmonica allowed for a full chromatic scale through the use of a spring mechanism. The spring was attached to a slide which covered the diatonic set of reeds and exposed the chromatic reeds when pressed with the index finger. The external spring design shown on this harmonica was changed in 1930 to an internal spring.  Alan G. Bates Collection, 2000.
