I have recently purchased a 1928 Chickering Ampico A baby grand (5'8")
and I am looking for a basic diagram of the components on the underside
of the piano.  I already have the 1919 instruction manual, but this
manual only has a few diagrams of the individual components.  I have
rebuilt upright players but this is my first Ampico and, before I start
to assess its needs, I would like to gather as much technical info as
possible.

Thank you,
John Kiszla
