It's especially interesting to hear of another one of this series
of Chickering Duo-Art pianos.  I can document five of them, one in
an art case.

In all I've seen so far they have had a standard (rather than a fan
system) Duo-Art expression system in them, and all but one have had
a model "B" Ampico pneumatic stack.  What's in yours?

In some cases the model "B" Ampico holes in the tracker-bar have been
leaded in and the Duo-Art expression holes added.  Has this been done
to yours?

What is the serial number of yours?  Where did it come from?
