Nice, used 5″ Jr Cowhorse Gag Bit from Reinsman. This one is either a #343l offering a thicker diameter mouth. Jr Cowhorse bits are some of our most popular selling bits. This one has a thicker, sweet iron mouth, in 3/8″ diameter with a traditional snaffle joint and contour mouth. Smaller rings than some to limit gag action, shorter shanks at 5.25″. The sweet iron mouth has rusted from use, but over all is in very good used condition.
