Reinsman traditional loose ring snaffle. 3" rings, 5" mouth. 3/8" 3 piece smooth with dogbone mouthpiece. 
 
"This bit is a variation of one of our most popular loose ring bits. The traditional lightly weighted rings offer excellent feel. The 3-piece ergonomic mouthpiece results in soft, even pressure across the tongue, bars and lips contacting different nervs than your traditional 2-piece mouthpiece."
