Vintage Western Show Bit. Medium high and wide port for lots of tongue relief. 5" mouth with 8" "S" shanks. Slobber bar is two pieces connected. Comes with metal chain curb. A nice concho on the near side. Missing the concho on the left. Add one on the far side or remove the one that is there and replace both sides with conchos of your choice.
Lower rein connector is made for rein chains. Rein chains are simple connectors between the bit and romal reins, they vary in styles, links, swivels, balls, etc. They send soft signals and vibrations to the horse that can't be achieved with the reins connected directly to the bit. They also protect your romals from getting wet when a horse drinks (LOL!). They refine signals from the riders hands to the horse. Great for precise riding.
