Billy Allen bits are some of our absolute favorites in western bits. This nice used, Reinsman Billy Allen #791 DL Reiner Billy Allen curb bit is right up our alley! Billy Allen mouths are very similar to mullen mouths, with a bit more movement and are connected with a center roller. Hard to find, smaller size at 4 7/8″. Mouth is all sweet iron, just starting to rust from use. Argentine style shanks that measure 7.5″. In very good used condition, nicely balanced bit. This is a great, kind, training bit. One that many horses would benefit from. Offered for way less than its new retail price!
