Dana Johnson, who along with Don Teach has done a lot of thinking
about tracker bar manufacture, sent me some pictures and gave me
permission to share them with the MMD.  I am sending one that shows
the inside of an original Wurlitzer tracker bar -- a view seldom
seen by anyone today.

I am preparing an article on tracker bars for the next issue of the
COAA's "Carousel Organ," and that picture and more will probably
appear there, along with insights provided to me by Dana, Don, and
Art Reblitz.
