Found at 1875 home. What is it exactly? I've heard the term "saddle badge", but not sure if that term is correct for this.... will send another pic when i get home later...
Yes, it does appear to be a saddle badge, although these kinds of ornaments were widely used on other pieces of horse tack such as harnesses and bridles.
I agree it's British made but, without a patent number, or deciphering what the word underneath 'PATENT' says, will prove difficult to date.
