I have a friend who got this bit with a horse she bought. The bit is a 5 1/2 inch. Regular sized horse bit...but it is like metal balls...completely jointed metal balls for the mouth piece. We refer to them as anal beads because it really does look like them. Can anyone help me identify what type of bit this could possibly be? Again it is a completely jointed bit. It goes bead, joint, bead, joint, bead, joint, bead, joint.
