Hello everybody! In answer to Kees Bimmel's question about the
scale of the 44-keys tracker bar of the Seybold Magic Organa, here
is a different way to view the scale. Shown here hole-by-hole,
this may be an easier way for your challenge.

The hole No. 1 starts from the driving spool side.

Best regards from France,
Jean Nimal
