Greetings,  After chasing down a bunch of false leads and a few helpful
hints, I think I have figured out the scale of the Wurlitzer 11.25"
rolls.  They are from Welte T100 rolls, with a few modifications and
some added sloppiness.

There seems to be no motor speed control track and the soft pedal is
a steady "on", using duct 91 instead of using a lock-and-cancel on
ducts 8 and 9.  Besides the above-mentioned differences, the bass
expression ducts are shifted by one hole: ducts 3 through 8 in the
Autograph scale become 2 through 7 in Licensee.

For MIDI files, I always convert from T100 to Licensee for consistency,
so I am expressing the conversion from Autograph to Licensee instead of
T100.  The bass expression codes in Licensee are 2 ducts higher than in
T100, and since the Autograph are one off from Licensee, they are also
one off T100, right in the middle, actually.

I do not have enough rolls to compare to be able to determine if any
bass notes may have been added to autograph rolls that would not play
in T100 or licensee.
