Good evening,  I started a collection of musical boxes, including
roller organs.  I bought a Schmider barrel organ of 24 notes, but
I have difficulty tuning it.  I bought a tuning roll, but it is
obviously not the correct one for my organ.

Would you have a diagram of the tubes showing the corresponding
note, or anything else that can help me to tune my barrel organ?

Thanks for your help.
