Thanks to all who responded to my recent post.  I now know why the
stack has extra outputs.  Art Reblitz remembered that originally the
DeBence style G Cremona was missing the piano stack.  Don Janisch
remembered selling the DeBences a piano stack from a style 20 or 30
about 40 years ago to put into a Cremona missing its stack.  These
put together explain why the player stack has unused outputs.

Now I need a photo of the modulant connections inside the case, and
a photo of the muffler rail.

Again thanks for all the helpful comments.
