[pianotech] Metal damper lever flanges with spring???

[David Pritchard]

For a Kimball Old Upright piano, I need the metal damper lever flanges  
that have the damper springs included as part of the flange.  These  
are like the metal butt flanges that break all the time, but have the  
damper spring integrated into the flange.  Schaaf part # 539, page 132  
of their catalog, but Schaaf says they do not have them and think they  
won't be produced anymore.  I have checked with PianoTek as well.  Any  
ideas where i can find this part?
