Just off the top of my head.  Basically I'd like
either the A0 string length (low A on a normal 88-key
piano) to be longer than the same note in the 1924 11
foot 8 inch Challen baby (yes, I know I should say
"concert"...) grand, which has an A1 string length of
9 feet 11 inches (119 inches), OR I would like it long
enough to have wound bichords as low as C1 or A0, have
the plain trichords start at C2 or lower, and have the
bass/treble break at B1/C2 or lower (wherever the
wound string/plain string break is, unless, if there
are wound trichords, it would be better to put it
either at the bichord/trichord break or in the middle
of the trichords.

Would it be on the Journal reprints CD by any chance? 
If so, what should I search for?
