Troy, I can't be positive that the "Catch All Tracker Cleaner" was
original factory or after market, but I had one on my instrument which
played the large OS/NOS Rolls.  I thought it was a super fine idea and
it never ever did it rob enough suction to affect the playing of the
piano.

Perhaps it was an option originally, but it certainly looked to be
factory installed and not something rigged up and installed by persons
unknown after the fact.
