<DIV><FONT face=Arial> The cap is a mortise cover, better
quality keyboards actually had a square mortise that went through the key and
than was covered, the notch you see is a mortise relief cut for the bushing
cloth, this allows the cloth to be folded over for a better 90 degree foldover
in the mortise. The reason you see the notch far back on the natural is because
they cut these relief cuts when the keys were not yet cut apart and that notch
will line up with the mortise in the sharps.</FONT></DIV>

<DIV><FONT size=3>Four questions I can't answer:</FONT></DIV>
<DIV><FONT size=3></FONT> </DIV>
<DIV><FONT size=3>1. This is a key stick from an old Kimball upright
which, judging from the trapwork, MIGHT have been a player, although there is
no folding control bar in the front, just a normal keyslip, and no other
evidence of "stuff" ever mounted to the case. Did some companies make
piano models that could optionally be fitted for a player mechanism or just
sold as a regular piano?</FONT></DIV>
<DIV><FONT size=3></FONT> </DIV>
<DIV><FONT size=3>2. Each key has an extra layer laminated to the top,
just the same length as the key covering (in this case a very tenacious,
rubbery plastic), so it sticks up about 3/16" higher than the rest of the key.

<DIV><FONT size=3>3. Then there is the inserted piece below that, over
the front rail pin area. Did they, maybe, cut the front rail slot all the
way through the key, then glue on little caps?</FONT></DIV>
<DIV><FONT size=3></FONT> </DIV>
<DIV><FONT size=3>4. And then there is the narrow notch, at the bottom
just left of center in the picture. I've seen these before but don't have a
clue what they're for. There is nothing different about the key bed, so what's
with the notch? </FONT></DIV>
