<DIV><FONT face=Arial size=2> Hello All: I am working on
a Baldwin upright with sostenuto, and it seems to be missing an intermediate
lever betwen the horizontal lever and the pedal screw (see diagram below).
The horizontal lever pivots on the vertical bar, causing the rod to pull the rod
down and the sos</FONT><FONT face=Arial size=2>tenuto system to go into
action. There are 3 screw holes in the horizontal lever at point A which
apparently is where a lever of some sort was connected, which then connected to
the screw coming up from the sostenuto pedal. The purpose of the spring is to
hold</FONT><FONT face=Arial size=2> the vertical bar in place, as that bar was
not glued or screwed onto the bottom of the keybed. Has anyone seen a
system like this before, and if so could you please describe the missing bar? My
guess is that it is an elbow shaped lever that goes from point A down to the
pedal screw. </FONT></DIV>
