David,

      I was asked to replace a set for Ronnie Milsap,  he plays with his boot
as part of the stage show,  and the keys were a mess.
      YAMAHA sent me a set of keys, by serial number, no  measurements were
taken.
     The keys fit almost perfectly!!  there was a little easing, and a slight
bit of  front spacing, but other than that,  it was a piece of cake.
    Ronnie's piano is a Disklavier, and even the blades on the bottom of the
key were indexed to the middle of the slots.  Amazing.............   I don't
think any other brand has achieved that level of tolerances.
