I recently acquired a 1920 booklet, "Good Times With Your Gulbransen,"
and it mentions a device called "The Leabarjan Player-Roll Perforating
Machine -- a portable instrument designed for the player-piano owner to
use in the home," with which one could supposedly cut his own rolls.

There's an illustration showing a young woman using the device; it's a
tabletop thing that looks like a small printing press.  It has a music
rack and she's hand-copying the music, note-for-note (seems like it would
be pretty time-consuming and laborious).  The company was located in
Hamilton, Ohio.  I'm curious to know if any MMD'ers have ever seen or
used one of these, and if they really worked?

The same booklet describes the technique of synchronizing a player piano
performance with a vocal phonograph record, and lists some specific
player rolls and phonograph records for which the rolls were deliberately
made to synchronize to the records.  Have any MMD'ers ever tried this?
I can put the list of rolls/records on the Digest, if anyone is
interested; there are about a dozen of them.
