Bass buttons on Steirische diatonic

[sprechen]

This is my first Steirische diatonic to work on and need some advice. Should these bass buttons be all the same height or was it made this way on purpose. None of the metal actuators appear to be bent. See photos.

Thanks

I'm not seeing what you're seeing. I may need new spectacles but more seem bent to me than not?

Yes, they are bent to pass each other. I don't see anything that would cause the one row to be uneven. I guess that the wooden buttons just are not seated down far enough, although none are loose.

They should all sit nice and level (see on
