<DIV>Hello Tom,</DIV>
<DIV> </DIV>
<DIV> The "Bowen-Henderson" Co. used this </DIV=
>
<DIV>"large drop screw" adjustment on top of the key </DIV>
<DIV>just in front of the center pin. It worked like a
dream.</DIV>
<DIV> After checking I found no excessive wear in the </DIV>
<DIV>bushing felt. This piano was made in the late twenties.</DIV>
<DIV> </DIV>
<DIV> An action model using this system will be</DIV=
>
<DIV>displayed at the PTGF. Museum at the 2005</DIV>
<DIV>Kansas City convention. </DIV>
<DIV> </DIV>
<DIV> In addition to this method the "P.A. Starck
Co"</DIV>
<DIV> had a system in the early sixties that used an inverted</DIV>
<DIV>upright let-off rail at the very back of the key to raise or </DIV>
<DIV>lower the back of the key. This would of course level </DIV>
<DIV>the front keytops. It used a standard capstan and</DIV>
<DIV>worked well but, we found it to be inconvenient. </DIV>
<DIV> </DIV>
<DIV>Regards,</DIV>
