Dear Mr. Kravitz,  My sister has a piano with a Phonola.  The piano
is a Roenish, and the Phonola is Hupfeld no. 42173.

The piano is being restored at the moment, but the technician who is
working on it sees there is a piece missing, and he does not know how
it should be.  The code of the mechanism is 1414.

I wonder if you could help her, sending us a drawing of how the
mechanism should be, and, in case the piece is identified, could you
provide her with a spare?  And of course, how much would all this cost?

Looking forward to your answer.  Thanks a lot for your help
