Herz Action Design

[Richard Moody]

RicB,
    The action diagram given in Dolge, "Pianos and Their Makers"
shows a completely different design from the one in your
attachment to an earlier post.  Dolge gives the date as 1850.  It
is titled "Erad-Herz Grand  Action, Paris 1850.  Sorry I don't
have a scanner but Dolge is still in print at least through piano
supply houses or the Univ. Library.
