In the future I'd better confine my observations to player pianos and
rolls.

An MDD subscriber who has been to Hildene and who knows much more about
player organs than I, emailed me to say the rolls he has seen at Hildene
are "non-registering 116N Aeolian rolls."

Mea culpa!  But even if I had known the right questions to ask, I don't
believe the guide would have had the technical answers.  Hildene is
still a great day trip, and possibly someone on the staff could answer a
well-phrased inquiry about the organ and rolls.
