Argentine Goodwater bit is horse bits with 5" (127 mm) sweet iron 3 piece broken mouthpiece with 4 copper rings and copper inlays. 5½" (139 mm) shank with the "Swivel Free System".
The antiqued finished shanks are trimmed with stainless steel dots.
A very good bit for introducing green horses to leverage. The broken mouth allows tongue relief. Very moderate effect.
