If what Tim L'Amoureux means by "roll reader" layout is tracker bar
scale, that should be given in "Treasures of Mechanical Music," by
Reblitz & Bowers. "Treasures" is not a book which many people would
have in their collection, but it is available at your local library
via inter-library loan.
The scale also might be in the even-harder-to-find book, "Mills
Violano-Virtuoso," by Reblitz & Kitner, but I'm just guessing here.
Perhaps Art Reblitz, its author, can say for sure.

[ Art subsequently sent the following email to Matthew:
Yes, it's in "Treasures of Mechanical Music," by me and Dave Bowers,
and the book "Mills Violano-Virtuoso," by Mike Kitner and me. It's
also in Appendix IV, "Musical Scales," of my book "The Golden Age of
Automatic Musical Instruments" where the numerical list is accompanied
by a list in order of musical functions, since the functions are
scrambled as listed in numerical order from left to right on the roll.
A lot of people seem to miss the fact that many of the important scales
from "Treasures" are also in "The Golden Age."
