Vintage Miwha Chromatic Harmonica with case Chromonica

Description

Vintage Miwha chromatic harmonica with case - marked "Chromonica" on the harmonica - comes with case and instructions
The instructions are in a foreign language and are folded, as they have been stored with the harmonica.  This was purchased at an estate sale and I am unsure of the details about the harmonica.  Looks to be in good condition.
