Lightly used and hard to find pony size Myler MB-33 Medium Wide Ported D ring, with chain. This 4.75″ bit is very lightly used, in one of Myler’s most popular mouth style, which gives ample tongue relief with a bit of correction. Has hooks for added leverage options. 4.75″ mouth, contour, stainless steel, with copper inlays to promote salivation. Per Myler:
The MB 33 is the mildest Myler mouthpiece in terms of tongue pressure. The generously wide port allows room for the tongue to pass almost completely under the bit. Because this mouthpiece does not rotate on to the tongue and the port is wide, it applies little to no tongue pressure, working primarily off the lips and bars. The port on this mouthpiece is only 1 ½” high, so it will apply little to no palate pressure. Because the MB 33 offers such a high degree of tongue relief, the horse that goes well in this mouthpiece has a trustworthy and consistent disposition, and is trained to work off the leg and seat as well as the hands.
