I have been following this thread with interest as I just finished
re-cutting the two-roll set produced by Welte (originally issued in
the T-100 Red version) and now transcribed for the Welte Licensee, i.e.,
Licensee adaptations of Welte 2165 & 2166 played by G. Romanowsky.

The rolls are long and take a special spool the diameter of which is
71.62 mm or 2.82 inches.  The spool fits in my Universal player piano
and should fit in most instruments.

The larger spool required special boxes -- nothing ordinary about
production!

The price is USD 95.00 for the set of two PLUS postage.  I will ship
outside the United States if you are willing to bear the cost of
shipping.
