I have to rely on people with musical ability when it comes to things like this.  My brother has been tuning pianos for over 35 years and played bass guitar and the trumpet.  The family put me in front of the radio and said "turn it on here, tune it there".  When I called and told my brother I had bought a small flute he didn't hesitate and told me to go to Cincinnati Fluteworks and see Pat.

 She is pretty terrific!  She also knows a flute form a piccolo and instantly diagnosed it as "nach Meyer"after Meyer.  Meyer was a famous flute shop in Germany and the instruments made by his students are not marked, so are "nach Meyer", but have all his characteristics.  

Pat pronounced my piccolo as in sound shape for restoration.  She said the cracked ivory head didn't effect its sound because there is a steel sleeve inside, the ivory is decoration.  She stabilized the ivory with an epoxy filler.  She soaked the wood in walnut oil, for a long time.  It's been recorked and has new pads.  No doubt she also did more little tweekings to make it ready to be played by someone with training.  I've enjoyed looking at it for a few months and I love the way it moves. Having spent time in a machine shop I can tell when something has been fitted by a pro.  You won't be disappointed.
