I have not a clue, they had at least 200 of them there... they look like they are mounted on bucking things... it is a little funny, they had another type also.. can't remember what it looked like, but this one, I'm going to try laying the quikwall over it like the sphere.. someone that owns cow farms probably know what they are for.
LOL they use them to practuce roping. they mount them to hay bales or saw horses and can practice throwing the lasso over the horns. Mostly for Rodeo now I imagine, but heading and healing, the art of 2 cowboys working together, one lassoing the head and the other the back leg so they could stretch the animal out was used for branding at one time. They do make nice art objects though. I have one hanging in my son's "cowboy" themed room.
