Hohner CBH 2016 Chromatic Harmonica

For fans of the remarkable Cham-ber Huang invention, the CBH2016 (2012), you are going to love this article that appeared in a 1975 DuPont piece. 

DuPont had just released their new Acetal Resin product called DELRIN and featured Hohner's CBH2016 as a successful case study of how the material could be used in close tolerance type production.
