While I have no first hand knowledge of what was made in Russia,
I do know that Welte-Mignon rolls were both recorded and sold there.
In 1910 the Welte-Mignon recording equipment was transported from
Freiburg to Russia and a great number of recordings were made.  Such
luminaries as Scriabin, Goldenweiser and Glazounov were recorded for
Welte-Mignon.  Many lesser known performers who might otherwise be
unknown were also recorded for posterity.

Additionally, many works which were "Russian" in nature were recorded:
Borodin, Cui, Korestchenko and Rachmaninoff are included.  Here we
find the first complete recording of Moussorgsky's "Pictures at an
Exhibition."  Most of the rolls numbered between 1900 and 2150 would
be considered part of the Russian recording sessions.  Check the
Smith/Howe Welte-Mignon book for a precise listing.  This was very
progressive for the time.

Likewise, the Welte-Mignon was sold in Russia.  I purchased a
collection of rolls offered to me from a Steinway-Welte piano which
was shipped from Russia to New York in recent times.  The rolls were
all without boxes and label information bore no particular inscription.
Some of the titles were translated and written in pencil on the leaders
in Cyrillic.  I have no literature from Russia.  I have often wondered
if a Russian language catalog was ever prepared.

I would be very interested in seeing any Russian Welte-Mignon literature
in the possession of any MMD member.
