Warren,
Thanks for the reply. I am familiar with the type of trapwork you describe.
Especially in the older Knabe's. This old Kimball dosen't show signs  of
what it had for the trapwork that operates the hammer rest rail for the
soft pedal. I just have the 2 metal rods. There isn't a hole or sign of
something being attached to the rail either. This old  thing has me
stumped.
Maybe somebody  on the list remembers. Thanks again.
Mike.
