Brass reeds can grow old and the metal crystallizes.  A new reed can
be hand made by removing the rivets holding the reed in place and
obtaining the same thickness of brass, cutting it to slightly larger
in size and filing it to fit the slot in the reed base.

Once the tongue fits the base, the reed will require tuning by filing
it.  The space near the rivets is filed to flatten the pitch, and the
end tip is filed to sharpen the pitch.  This is extremely time
consuming.  I have made a few, and discourage anyone from trying unless
it is the last resort.  Better to find an old reed of the same size,
and tune it to the scale of the organette.

I suggest you contact: Daniel Tenerowicz, who specializes in reed
organs.  He might have the exact reed you are looking for.
