We now have heard of three acrylic tracker bars, one each for
Wurlitzer 105, Wurlitzer 146B, and a DeKleist organ playing
Wurlitzer 165 rolls.  One has to wonder if these were all made
by the same person?  By whom, is the question.  Does anyone have
any information on other similar tracker bars, or who might have
made them?
