I was at the hardware store today looking at what little horse stuff they have (they had pure neatsfoot oil, I should've gotten it!). They had a leather mouth loose ring snaffle, and some other weird snaffle. It was a loose ring, but it was a straight bar. The mouthpiece was a hollow tube of metal that had holes in in, almost like a wooden flute, but metal and holes on both sides. I don't have pictures of it, but if I go there soon, I will try to get some up.
Any idea what kind of bit it is?
