I am looking to buy some old Aeolian parts.  The two things are

1. An Aeolian spoolbox that sat above the keys in the grands, and
has the 88-65 note mechanism that Aeolian built in;

2. A Grand Duo-Art expression mechanism from before 1920 or so.
Before then the expression mechanism was a two-piece unit, and
all the later ones were the familiar one-piece unit.

Thanks, Randolph Herr
