Last year I purchased an "A" roll player that was listed for sale
on MMD.  The player came complete with all valves, tubes, and it
is in great condition.  This unit controlled a calliope on a
paddle-wheel excursion boat.  Assuming the calliope was a 43-note
scale, does anyone have a scale that shows which notes go with which
hole in the "A" roll?

I am about to build a wind chest using direct action magnet valves
driven by the two 16-wire cables that came with the player unit.
They are on a 12-volt power supply.  I have an "A" roll tracker bar
scale, but it does not name the notes it plays.

This is my third organ build and the largest one yet -- still an
amateur.
