Hi Group,  I rebuilt the bottom pumper bellows on a 1912 Wurlitzer
nickelodeon 5-roll changer; pretty straightforward, came out real
nice; mandolin/soft, loud pedal controls pretty obvious.

There are a few sub assemblies located on top of the stack that are
puzzling me.  One has a wire going to the transmission frame attached
to a spring closed pneumatic that doesn't seem to serve any purpose at
all.  And for the life of me, I can't figure out the shut-off circuit.
I know it's triggered by the first T-bar hole, ditto with the end of
roll re-roll triggered by number 75 T-bar hole.  I recovered that
trigger pneumatic and I see how it works easily enough.

For something so obviously "Duh" I am a bit stumped.  There is one
supply tube coming out of the stack on the left side going to a block
on the top of the stack.  All of the tubing was missing or macaroni
when I started the project.  The changer works beautifully and is
a marvel to watch.  Any thoughts?
