  Hi,

  Erard used this system on their brass hammernuts I think from the =
second half of the 19th century on. It works well but is sometimes hard =
to regulate.
  Maybe it was to expensive to produce?

    I once saw an old piano in Del's shop that had screw adjustable key =
bushings. It appeared to work beautifully! Anybody else seen this?
