Right, I think I understand your thought process on the Iyesà Shekere quiro. I'll keep an eye out in my transcriptions and sources. If I find something I'll respond here. I never really dug real deep into the shekere Iyesà as, to me, it just sounded like a lot of swishing without noticeable differentiation.
Here's what I have from my friend and teacher Dave. I don't consider this a quotable source as his purpose in writing the Iyesà this way was to create an invento, like I did, for playing bells and drums along with it. But, he was deriving it from an Iyesà quiro.

Looks like what Dave wrote on the bottom two gourds lines up with this one, and then there's just a downbeat high shaker as the third.
