This is a nice quality bit! From the team up of Reinsman and Martha Josey, the #719 Go Around offers a 5" medium ported mullen mouth in sweet iron, that rusts to offer a nice taste for your horse and gives ample stability. Offers gag action and a C shaped shank that measures 6.75". In excellent used condition.  Per Martha Josey:

This bit provides excellent handling qualities. The shanks help the mouthpiece stay in place and the rider gets just the right amount of gag action. This bit can really package a horse up, keeping him collected and snappy in the turns. Use this bit for correcting a horse that elevates his nose or drops his shoulder or helping a horse use his rear end rounding him out in a turn.
