[pianotech] Fwd: Crown Upright Question from the Dark Side

[Dale Erwin]

 The pedal in question is a Mandolin
Attachment that has little wooden "balls" hung on loops of string. When the
pedal is activated the little "balls" are place in contact with the
strings. The vibration of the string energy makes the little "balls" bounce
on each individual string and it sounds like a mandolin. As I recall the
Yes and a very cool sound it is too. I think all Yamahas Diklaviers should have one. Where do I get the tiny wooden balls
  I'll make a retro fit kit, we'll go into production next week....probably nahhhh tt

The following was gleaned from the Dark Side:

Subject: Crown upright
Message: Hey everybody,
I have a George P. Bent "Crown" upright that has four pedals that I am
rebuilding. This is the first time I ran into a four pedal piano. The first
one is the sustain, the second one operates the mute rail, the third one is
the one I have no clue about, and the fourth one is the soft pedal that
pushes the hammer rail forward. When the hammer rail is pushed forward,
there is also a compensator rod that takes up the lost motion as the rail
goes forward.
The second and third pedals have a slide notch to the left so that these
pedals can be held down while playing.
The linkage that is still on the piano operates over on the treble side of
the piano and it PULLS down when the pedal is depressed and it is missing. 
Does anyone have a clue of what the function of this pedal is?
It is definitely not a sostenuto."

Hopefully, you are a "duo-member"<G> The pedal in question is a Mandolin

rail that holds the "balls" pivot to get them in position.
Hope that helps. (or maybe falls on deaf ears, as usual)
