For the proper show attire these are common and I ride in one very similar and ofcourse with a curbstrap or the shank wouldnt have any effect
They are simply call Walking Horse Bits- The shank is pretty standard but the middle can be all sorts of things like jointed or a straight bar with or without a variety of ports- all the way to a bicycle chain (If you use one I'll hunt you down haha)
I actually don't use a bit on mine and never have. We got her at 6 weeks old and I did a lot of flexing with her until I could ride her, at 3 years old. I didn't start her until then because she had an injury to her leg before we got her. She was also lacking in some nutrition which caused her development to fall behind. At first I rode her in just a rope halter and now I ride her with a bitless bridle.
If I was to use a bit, I would have started her with a snaffle and moved her to a combination bit, snaffle type mouth piece with shanks. That's what we use on the rest of our horses. Posted via Mobile Device
