Hello Phil F. and Richard B. 

    Phil !  there are at least two (2) other  methods 
that  were used  in the  past  that  were successful. 
   Sorry Richard !  but both are viable
  
     The latest one used was in the " P.A. Starck "
 verticals in the 1960-61-62 time frame.  This was 
also after the J.P. Seeburg Organ  Co. bought Starck.

      Under the key at the very back, an upright
 ( jack) let off rail was secured to the a wooden 
rail with  a let-of button and felt facing up under 
each 
key. The key height was adjusted by turning the
let off button up or down. This was in their consols
and spinets. 
   The down side being that after this was adjusted 
you then had to adjust the capstan.
 
    
      The second method was in a  "Bowen-Henderson"  
 1920s grand and perhaps others. This method used 
a  "Jumbo" type drop screw that was inserted thru the 
key just in front of the center rail pin.  Of course the 
adjusting end of this screw was on top of the key.  
There was no punching of any type.   There was a 
strip of action cloth about a quarter inch wide in front 
of the center pins.  And to answer the most logical 
question, no,, there was no pulley keys and the piano 
was well used. 
     I demonstrate one of these in the  
"Action History Class" that I give for the 
PTG. Foundation

Regards,
Jack Wyatt
