Reinsman Pro Roper. Stage C. 7" Cheeks, 5 1/2" mouth. 1 3/8" low ported chain mouthpiece.
 
"The German silver cheeks have a no-pinch ball hinge for good control, good to lift the head and shoulders, pull the horse a little more in the turns, or take more hold in the box. The 1 3/8" low port chain mouth provides some tongue relief and conforms to the shape of the horse's mouth for even dispersal of pressure. An excellent bit for timed events."
