[pianotech] Old Kranich and Bach Grand

[Thomas Cole]

Clark,

The main difference in these K & B wips is the distance between the wip 
flange and jack centerpins. A dozen years back I was able to get a 
similarly configured wippen to fit by taking a 1/4" section out of the 
beam and super gluing back together. The piano is still playing nicely 
today... well, the A#7 is playing nicely ;-)
