Joel, Looking at the picture, the pipes B7, C8, and D all appear
to be the same length. They may be replacements. Assuming that
the scale you came up with is correct (and I believe it is), I'd
see if I could get those three to come in to some "relatively"
pitch -- i.e., not necessarily A-440, but correct relative to each
other: half step, whole step, whole step.

It surely looks like that D ought to be a bit shorter. I would
go ahead and tune the C with no coning or flair. Now try to bring
the B and D into pitch to that. Find out what relative pitch you
are at, and then trying tuning the rest to that.

This will surely require a lot of back-and-forth on tuning, but I
would not expect this serinette to be at any particular expected
pitch like A-440 or 435. Just find a pitch where everything will
be correct relatively.

The bottom 6 pipes look to be fully open with very little coning.
They can surely be flattened more in pitch, and maybe enough to
match the pitch of those top pipes. Trimming would in my opinion
be a last resort, which I have done.

Another place to look would be the toe holes. Are all the pipes
speaking with the same volume? Opening the toe hole on those top
pipes (assuming they are not speaking loudly) might help sharpen
the pitch slightly. Good luck.
