Oh, actually, I had taken the cover plates off to see and show its interior. It is playable, but it’s hard to figure the tuning — at least for me and my musician friend.

About the music, anything goes. It’s for fun anyways, and thus I feel like trying to use this one I already own.

Thanks for the insights.

Yeah, indeed, though there is no leather reeds.

Oh, I’m sorry for the misunderstanding. It is like that because I had taken it apart to understand and show its interior. Nonetheless, though, they have nothing stamped on them.

About the tuning, don’t chromatic harmonicas have a lever and tremelo and octave ones have a double reed plate?
