Solon, we have that same bit hanging in our tack room. The shanks on mine are shorter but the mouth is the same. There was only 1 horse that was ever used in it and that was the old buckskin horse that I rode growing up. The only time it was ever used is when Dad would team rope on him. He was a very different horse with a personality like I have never seen. If Dad was riding him, no matter what he did, sometimes Buck would just ignore him completely and go the way that he wanted to. For the first 5 years we had him, we had to keep a solid chain tie down on him to keep him secured at a roping or show. He would just nose through and break everything else. If he could get his head over it, he would climb it. It didn't matter if it was fencing, pickups, trailers, or people. For the kids, he was the perfect kid horse and always went where we told him but with an adult, he was a whole different story. He was the type that the only way to get his attention was to really inflict pain on him. Dad tried everything else but Buck would almost just laugh at him. He was a true outlaw horse that Dad saved from the killer truck and he did belong there. He was the one exception to the rule though. No normal horse should ever need anything more harsh than a simple snaffle or grazing type bit.
