Vintage M. Hohner Tango Harmonica. I don’t know too much about this item so some of the details might be incorrect, but I believe is this a pre-war model. It appears to have 20 holes and 40 reeds and I believe is double tuned to the keys of A and D. Some of these details might be wrong, but this is just what I could find. I am unsure if it works as I have not tested it meaning this item is sold as is. The harmonica itself has some wear to the metal, but nothing serious and it includes the original box which does have some damage. If you have any questions feel free to inquire.
