Stainless steel with single jointed mouth. Referred to as the “Kimberwick” in the USA and sometimes known as a “Spanish Snaffle”.
As with pelhams and Weymouth bits, the bridle cheek pieces are attached by the eye at the top of the bit to produce a more direct poll action. The slotted cheeks allow the rider to alter the rein position to increase or reduce the curb action. Comes complete with double link curb chain.
