Old (50 years old +) Ayrshire Dairy Cow Horn Trainer. This is still used with Ayrshire dairy cows to train their horns to grow upward. The bolt and the horn loops are made of brass and turn freely. The back plate is steel and slightly rusted but functional. The strap (leather) to hold the trainer to the cow is in bad shape and needs replacement.
Interesting old Dairy Collectible.
