This is a Vintage OPERA Harmonica with its original tin case. This harmonica is in the key of C which you can see printed on the side of the plate. The instrument was made in West Germany. The tin case shows that it was made in the Germany - US Zone. Both these items are well used. The harmonica can still be played even though the metal plates on it are slightly dented.  The tin is scuffed and tarnished but still opens easily.
