5″ Myler Level 3 Flat Shank Medium Narrow Ported barrel curb, in hardly used condition. Sweet iron mouth. Flat Shank with Sweet Iron Wide Ported Barrel (MB 43MP, Level 3) Copper Inlay. This mouthpiece is made of polished Sweet Iron which naturally oxidizes or rusts. Harmless to horses, it has a sweet taste and promotes salivation. Offers great tongue relief for your horse. Has not started to rust, very lightly used Per Myler:
he MB 43MP 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 ½” high, so it will apply little to no palate pressure. The MB 43MP is the mildest of the Level Two-Three mouthpieces in terms of tongue pressure, just one step below a Level 3 mouthpiece. Sweet Iron mouthpiece oxidizes and encourages salivation.
