Paul;
 I have one of these "steep shelf" Knabe thingees in process right now.  I 
don't know the string breakage history on it but I do have a couple of 
questions.
  On your customers Knabe was there a brass, or steel, counter bearing bar 
right at the point where the strings nose dive down to the agraffes? Also in 
the upper tenor section, between capo and tuning pins, was there a counter 
bearing bar?
  There is a secondary bar, felt covered, right in front of the pins but 
where I am speaking of is right where the strings dip down from the plate web 
to either capo or agraffe.

  Reason I'm asking is the Knabe I am working on has a counter bearing bar in 
the treble but there were none in the upper tenor section(to capo) or the 
tenor section(to agraffes).   There are what appears to me to be the marks 
left by a bearing bar but as this piano has already been restrung once I 
don't know what was there. I have milled two bearing bars to fit in these 
sections but thought I would ask if you, or anyone else, can recall whether 
there were any actually there.
 Thanks.
