Anybody have any Wangerin player organ rolls (1920-1930's)?  They are
the same as standard player piano rolls in width and flanges but have
side holes on both right and left for registration.  The tracker bar
has 88 holes spaced just as standard player piano rolls.  The organ
plays 61 notes and I guess the bottom and top octave area is where the
extra mechanical holes are.  I am thinking that it will play standard
rolls if I tape off the top and bottom extra holes.  Any suggestions?
This is a three-rank mortuary pipe organ that I just bought for
restoration.

Thanks, Mark Henderson
