[ Editor's Note:  I sent e-mail requesting more information on the USENET
 [ News posting which Will Wild forwarded to us for digest.95.11.22.  Below
 [ is the reply I received, which provides more details about the mechanism
 [ in question.

Celcilan is the brand.  The push-up was made about 1904 before the
manufacturers knew how to build the mechanism inside a regular piano.  It
uses regular 58 and 65 note rolls (the type that were popular before about
1910).  It is all pneumatic and uses the same type of mechanism as a standard
player piano.  It is located in Sylmar (near Los Angeles).

Let me know if you have any other questions.
