Horse brass fits the bill for Jubilee

Look what I found at the Black Country Boating Festival!

I was looking through a box of horse brasses, and the first which caught my eye was one which had "Jubilee" and the dates 1952 and 1977. That would be good, I thought, and I bought it immediately. I carried on looking, and then found this one which was even better as it had no dates. So I swapped it.

It's perfect for Jubilee. The only thing is, I'm not sure where to put it.
