ohh sid boots. That would explain why I didn't reconize them. I'm an english rider and I'm not very educated on the whole reining thing. As for the breast coller, I'm very sure that my farrier put them out to throw out, but just in case I'll ask him next time I see him. My farrier has a horse trainer wife that seems to be very wastefull. In the box there was TONS of stuff. Professional choice boots, splint boots, a couple of bad bridles, 2 more breast collers (not like this one at all they were completely leather and pretty stiff) an english girth and reins, plus more and more. Last year my dad recovered 3 english saddles and some brand new turnout blankets from their dumpster. Not all of the stuff from the box was in good shape though. Some I had to throw out myself.
