<html> <body> Hi, Patrick, Is there any evidence of some kind of mounting setup on the bottom board?  Also, where is the pivot for the sostenuto pedal itself located?  If at the back, that suggests one kind of mechanism to activate the long lever.  If toward the middle, another. From the pictures, it looks like there needs to be another pivot point.  I seem to remember some kind of elbow or dog's leg, as you suggest, but cannot quite bring it to mind. Best.
