Horace: It does appear that whatever was screwed onto the lever was attached directly above at the bottom of the keybed, where there are two empty screw holes. It seems that there must have been something there to keep the sostenuto from engaging without use of the pedal, and also to keep the assembly aligned in place, as the vertical bar is only held in by the pressure on the relatively weak spring. The 3 screw holes on the bottom of the right end of the horizontal lever are countersund,which would seem to mean that the screws there came up from below and went into some kind of wooden piece above. The interesting thing is that there are 3 holes in the lever, but only 2 holes above in the bottom of the keybed. Maybe there was a hinged and spring-loaded two-piece bar that rode on the graphited end of the horizontal lever that both kept the assembly in place and returned the horizontal bar to its place when the pedal was released? And also an elbow-shaped piece going over to the pedal? This is starting to sound as strange as a Chickering ! Patrick -------------- next part -------------- An HTML attachment was scrubbed...
