In answer to Lee Walker's question about the Autoplayer air motor,
the world was and is full of piano tuners that become really
grumpy when the player things get in the way of their work.

When you undo the latch it allows the air motor to tilt forward
so the tuner can easily access the tuning pins without completely
removing it.  Thus, if one is lucky, the piano tuner may not charge
as much as he would have otherwise.
