What bit is this?

I love bits and am super fascinated by them, so when I saw this one on a FB post I became very curious! Does anyone know what it’s called and the mechanics of it?

Looks kind of like a version of a Goyo Aga bit, which is a leverage bit that can be adjusted based on where you put the reins on the various rings, but, I have never seen this exact one!
