I am looking for resources or guidance on how to tune the small
metal pipes on an antique Serinette (Bird Box) that I am refurbishing.
See attached photo.

It appears that the pipes produce a diatonic scale with 10 notes,
C7 through E8. The problem is that the top three notes are very flat
and I cannot get them tuned to pitch without some major modifications
to the pipes.

Any help would be appreciated.
