I am in the design process of designing a piano/pipe organ combination
that will play several different types of rolls.

It will play : 88-note, O , OS/NOS , Kimball player organ (NOT the pipe
organ), A , G , 4X , and 65-note.

My question is: is there a decent source for "M" rolls? ("M" rolls were
used by Marquette Piano Co. for the 'Cremona' line [for those who didn't
know]).

I would like to have the ability to play as many rolls as possible.

The machine would have 2 spoolboxes - one with an 88-note tracker bar
(actually a WELTE t-bar because it has the extra holes on the ends to line
up with control slots on different rolls) and a 65-note tracker bar.

I don't plan to to be able to play "H" rolls, because they won't fit the
spoolbox.
