I have located a very unique player piano.  It is a 76-note "Boudoir"
made by the Columbus Piano Company, Columbus Ohio.

This is a very small 76-note upright, with a surprisingly loud tone.
Sadly, the stack and pump are gone.  The only information I can find is
that this piano was the forerunner of those made by the Lindenberg
Piano Company, and possibly had an Amphion stack.  And it is fairly
rare.

If anyone has seen one of these, I would like to hear from you.
