that button is actually a bar or flat plate that slides
so it will play two different keys which is nice for stepping

Actually I knew it caused a mechanical part to move, but I didn't know what else to call it but a button.

I found it.

On the outside of the case, it says: Koch-Harmonica, CHROMATIC, Made in Germany

On the Harmonica itself, it says,

THE "CHROMONICA"
(chromatic harmonica)
Made by M. HOHNER Germany

It's in "C"

I also have a little "Blues Harp" made by the same company.

Also in "C"

Did it ever get you any lovin' from the girls?

LOL
