Una Chorda...again

[Joseph Garrett]

What I should have asked was....when was the una chorda PEDAL first
introduced? That would have been more specific to my query, as there were
mechanisms, (ie levers, etc.), that accomplished the physical shifting of
the action. As I understand it, there were such mechanisms in harpsichords,
prior to the invention of the piano. Is this correct?
