Monz asked:

< 1. *exactly* how did Harrison specify his tuning?
did he give a measurement for the "5th", or for the
semitone, or exactly what?

2. and did he use something that looks like a ratio,
which is what i have on my webpage (which i believe
i got from you, Charles)?

2^( (2pi + 1) / 4pi )
or
2^(1/2 + 1/4pi)

or did he actually say that the "5th" is 600+300/pi cents?>

Actually none of the above specifically.

He described the tuning as larger and lesser intervals:

i.e the II and the bII intervals.

Although as you suggest, all you need to calculate any of the intervals is a suitably stated formula containing pi and an octave ratio of exactly 2.

The word for word answer to your question is on this page:

I'll answer the other items later....
