From my father's 2008 estate's harmonica collection:

The Hohner Chromonica 260 is a chromatic harmonica that was fully developed by 1938. 

 It has a 2-octave chromatic range, a pearwood comb, and perfectly tuned brass reeds. It also has chrome plated covers and wind-saving valves for greater tone volume. It comes with a durable case and weighs 155g

Good condition. Free shipping with care
