Lightly used and hard to find Myler MB-43LP Low Narrow port Kimberwick, with chain. 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. Per Myler:
The MB 43LP does not rotate on to the tongue, but instead sits solidly across the bars and lips of the horse’s mouth. The port is narrower than a Level 3 mouthpiece, but still offers room for the horse’s tongue to pass under the bit. Because the port is narrow, when the reins are engaged, the horse will feel a slight pressure on the outside edges of the tongue — a gentle reminder rather than a strong reprimand. The port on this mouthpiece is only 1 ¼” high, so it will apply little to no palate pressure. It is the mildest of the Level 2-3 mouthpieces in terms of tongue pressure, just one step below a Level 3 mouthpiece.
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.
