Hello MMD,  I "inherited" a tracker bar about 40 years ago that has
98 holes plus the standard offset roll tracking holes on either end.
This tracker bar has all the same size holes, 9-to-the-inch, and is
the exact same size and length as a standard player piano tracker bar
except that it has an extra 10 holes.

Does anyone have any idea what instrument this tracker bar was
originally used for?  It's more for curiosity than anything else.
The tracker bar is going to become an O-roll tracker bar for an
orchestrion I am in the process of building.  The extra 10 holes are
a bonus.  Which brings up one more question.

I am going to use the extra holes to bring in additional instruments
and was wondering if there was a hand-operated single hole paper punch
available to add extra holes to an existing roll?  For all the purists
out there, these are all reproduced O-rolls so I am not cutting into
a Picasso.  I've done this in the past with an X-acto knife but it
never looks very good.  Thanks for any help.

Thanks,
Tim L'Amoureux
