Shires Jr. Cowhorse Sweet Iron with Rollers

This bit goes by a Jr. Cowhorse and a Tom Thumb. This small gag also works with leverage like a shanked bit.  This Shires Jr Cowhorse is made with sweet iron bars, a  dog bone mouthpiece with multiple copper ring rollers. The sweet iron oxidates in the horse’s mouth to taste sweeter and have better acceptance with the horse.
