Hello!  A friend of mine bought a very early 11-1/4" Polyphon wall
hanging automata.  It is a double comb machine, with the very wide,
early teeth, 27 on one comb, 28 on the other.

All the leads are lacking, and because of that it needs complete
retuning.  Can anybody help me with the tuning scale for this special
model?

Thank you for any help
