Key structures ...

#4...continuation of sharp mortise as the keys are made as one unit *then* sliced apart.

#3...sort of...again has to do with the cutting process.  This is found on many keys.

#2...yep, seen this on lots of keys, although generally not in combination with #3.  I think it has to do with a more stable glueing surface.  Any comments on that one anyone?

#1...Kimball made some players with no fold down keyslip.  There was a drop open door.  Therefore it is possible to have replaced the original with a conventional keyslip.   There should be other signs within the case like empty screw holes.  These may be minimal and could be limited to just a couple in the bottom as part of the pump mounting.

  Four questions I can't answer:

  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?

  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. Wassup widdat?

  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?

  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? 



  Thanks.
