John,  I feel that your "find" might need special consideration.
The very early Ampico installation is quite different from what most
people consider to be an Ampico "A".  It is my opinion that this
piano is more than just another piano that needs to be restored.

Ideally, a collector who desires to preserve the early beginnings of
the Ampico should be the ultimate owner.  In other words,  the owner
who just wants a nice reproducing piano, may be disappointed in the
performance of this piano and may be inclined to neglect its care.
I say this believing that the expression devices are the very early
type that clog up and need considerable on-going attention to perform
correctly.

If this piano is indeed 1913, it is historically significant and rare.
It needs to be preserved and well cared for.  Matching it to the right
owner is the challenge.  If that is your interest, by all means, get
the piano.

Jeff Morgan is an expert in Ampicos and is very familiar with these
early designs.  His AMICA Bulletin articles cover early Ampicos in
great detail.  Perhaps you could chat with him.
