Hardly used Myler MB-33 Medium Wide Ported Kimberwick, with curb chain hooks. This 5″ bit is very lightly used, in one of Myler’s most popular mouth style, which gives ample tongue relief with a bit of correction. 5″ mouth, contour, stainless steel, with copper inlays to promote salivation. Comes with curb chain hooks. 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.
The Kimberwick is a “D” shaped stainless steel ring with a purchase for the headstall and two attachment options for a single pair of reins: the direct (snaffle) and the indirect (curb) positions. Comes with curb chain. Like the Pelham, the purchase creates a fixed cheek so the bit is held in the correct position. The rider can choose the direct (snaffle) position or indirect (Curb) position for rein attachment. The Indirect Rein position adds very little to mild leverage. Designed to be used with only one pair of reins.
