This is an old steel Hanoverian horse bit with quite a dark patina. I wrote a short blog about Hanoverian bitshere It has a medium height port with three rollers on each side of the port. The rollers still turn freely. There is a hinge on one side of the port but not the other - this is unusual, perhaps the bit was a special commission. It has curved cheeks or shanks which turn. The original curb hooks survive.
Dimensions : Mouthpiece 5" (12.8cm), total cheek length ( not including curb rein rings) 8" (20cm) Weight : 514g (1lb 2oz)
