This is the Hohner No.364 Marine Band Harmonica in the Key of G. Made in Germany.

I would guess this harmonica is from the early 70's but I'm not a Harmonica expert by any means. The guide book is copyrighted 1971. See pictures for condition.

Comes with the HOW TO PLAY THE MARINE BAND TYPE HOHNER HARMONICA Guide book. The book gives instruction on how to play, methods, special effects, maintenance and a list of songs to practice. From the guide book, learn popular songs like Hot Cross Buns, Good Night Ladies and just in time for Christmas, Silent Night.
