An Old Pony Bit
This bit is very unusual. It is very small so was for a pony, It has leather biscuits at the sides. the bar is straight and covered with leather. The brass sides would ave reins attached to the end of shank and the cheek pieces to small loop near the bit. Hard to know if it was gentle but clearly was made especially for a pony with a problem.
