Hi, I am a college student taking a technology class and I was given the task of identifying a tool that i believe was used for horses. My professor says the tool was obsolete by the 1920's. That's the only hint he gave me! lol! I was hoping you could take a look at the attached photos and get back to me if you know what this thing is or what it could have been used for. I'm not even 100% sure it was used for horses but have a hunch. Thank you in advance.
