Key level puzzle-report back

[Gary and Jean Isaac]

Thanks for the responses on the key level problem.  I went back to the 
piano today and found the answer:  in moving the piano the right back toe 
had come off.  This allowed the whole internal structure to shift 
downwards from the case so that the treble portion of the keyboard was 
raised too high.  What I didn't do, since I had no one to help, was to put 
the piano on its back to find out why the case was not fixed solidly to 
the internal structure.  Is it not supposed to be?
