Slowly We Turn

 We picked up an Auto Piano player nearly thirty years ago, and it has been patiently waiting for us to tear into it.  We finally got up the gumption to start, and have begun tearing down the pnuematic stack.  The pneumatics are glued in three ranks and it requires patience and care to break them out without actually breaking them.

 The pouches are made of fine, soft leather, and they appear to be in great shape.  When the player roll uncovers a hole in the bar, air comes down a tube and inflates these leather discs from the opposite side, which causes them to push on a valve, which opens the vacuum chamber to the corresponding pneumatic.  It actually isn't terribly complicated, but there is a lot of repetition.

This is the place to get your player parts.  I was fortunate to visit this warehouse/store back in the early 1970's.  I sure am glad they are still in business.
