Hi All,  Tom Hutchinson's posting causes me to want to ask
a couple of questions.

One: What type of music rolls does the unit use?
Two: How many instruments, besides the piano, are involved?
Three: Are lock-and-cancel valves involved?
Four: Is the unit a "Quarter-Oleon" or a "Nickel-Odeon"?
Five: Are the various sequences controlled electronically,
      pneumatically, or in combination?

Musically,
John A Tuttle
