Reinsman traditional loose ring snaffle. 3" rings, 4 1/2" mouth. 3/8" smooth copper, single joint mouthpiece. 
 
"Stage A. Traditional Loose. Traditional rings. The 3/8" is a perfect all-around mouth. Copper creates moisture, packs well, and keeps well in high salt areas. Copper is a soft metal, watch for excessive wear. Mullen relief mouthpiece creates even pressure across the bars and mouth to eliminate the nutcracker effect. "
