Tim L'Amoureux asks about a 98-hole tracker bar.  I have only seen
one Welte and this had such a tracker bar.  The Welte licensee was
made by Kohler and Campbell who produced the Standard action and
Autopiano parts.

The offset tracker holes almost guarantee the Standard/Autopiano
tracker, and the 98 holes of equal size guarantee the Welte.  Put all
together, I would have London to a brick on it being Welte Licensee.
