Very lightly used 5″ Myler twisted D ring Comfort snaffle with hooks. This is actually a long discontinued style, despite its popularity. The mouth is twisted over the bars, smooth as its gets to the center, with a smaller center roller. All Stainless Steel  with 3 3/4″ D ring cheeks, with hooks to add various leverage options. This one is most comparable to the modern Twisted Narrow Barrel Comfort Snaffle (MB 01T, Level 1) Mouth 5″. Very lightly used. Nice bit that isn’t as ‘harsh’ as the current MB01T.
Per Myler:
The MB 01T twist has no pronounced sharp edges, and the twist is a mirror on each side of the center barrel to provide a balanced feel for horse and rider. It is the Myler alternative to the traditional single-jointed mouthpiece commonly used in snaffle bits. The MB 01T rotates onto the tongue to apply concentrated tongue pressure at the center barrel, but because the mouthpiece is curved, it wraps around the bars and lips instead of pinching. The barrel in the center applies approximately the same pressure on the tongue as a traditional single-jointed mouthpiece. However, the barrel distributes the pressure more kindly and allows for each side of the bit to be used independently.
