Hi Everyone,  Does anyone have the tracker bar scale of the Magnus
player organ?  I have a couple rolls and want to scan them.  If no
scale is known, I will scan in different configurations until it
sounds right.  It was stated in an earlier MMDigest that the roll has
29 holes, and that seems to agree with the width of the paper, 9,5".
The hole spacing is 5/16" or 0.310".
