Found this at a flea market today, was actually going to use it on my horses, then cleaned it up and spotted a mark on the headstall "rock island 1918 G.H.W." Looks like a halter with cheekpieces attached to a heavy padded noseband and over the noseband leather is a heavy metal bars held down by small leather buckles, in the center of this is a metal swivel ring. (You would attach your lunge line to said ring and the horse would warm up around you in about a 20 meter circle) There is other marks G.W.H. and J.B. on it as well. I will try to upload a picture as soon as I get it cleaned.
