[CAUT] Friday puzzler

[Roger Jolly]

Hi Paul,
                   Check the sustenuto tab with respect to the sustenuto 
bar to make sure you have clearance.  Operate the sustenuto pedal a few 
times to see if the damper head blinks.
Make sure you clean all rep spring grub slots, and polish spring tips for a 
big improvement in touch.  This vintage used tallow for lubrication and has 
long since gone hard,

Have fun.
Roger
