A notable exception to the traditional reed plate design is the all-plastic harmonicas designed by Finn Magnus in the 1950s, in which the reed and reed plate were molded out of a single piece of plastic. The Magnus design had the reeds, reed plates, and comb made of plastic and either molded or permanently glued together.
