Very lightly used 5″ Stainless Steel D Ring with Hooks with Stainless Steel Ported Barrel (MB 41PB, Level 3) Copper Inlay. Level 3 with a correction port that offers some tongue relief, hooks for mild leverage option, and a point that offers an option for a curb chain. This bit allows the rider/horse pair many options for their training needs. Has inlayed copper to promote salivation. This is a discontinued model, as the newer version of this model has a smaller roller and straighter mouth piece. Please note that Myler’s with a more anatomical mouth will measure a bit larger laying flat. Per Myler:
The MB 41PB is a Myler correctional mouthpiece, which is a ported mouthpiece that collapses on to the outer lip and bars, and rotates on to the tongue. The port, although narrow and somewhat low, allows room for the horse’s tongue to pass under the bit. When the reins are engaged and the mouthpiece rotates on to the tongue, it applies two concentrated points of pressure on the tongue for quick control. Because this port is only 1/2″ high, it will apply little to no palate pressure. Sweet iron mouthpiece oxidizes and encourages salivation.
