Decorative brass cap or cover? How old and what is it?

[FreeBirdTim]

Found this next to a stone wall in the woods. Can't figure out what it is, so I could use some help. Thought it was a button at first, but the hole in the middle ruled that out. It's slightly larger than a half dollar and it's very thin brass. Has a floral decoration on the front.

Here's a couple of pics. Any ideas?

Maybe with what appears to be horseshoes in 4 positions maybe part of bridle rosette

Rosette of some sort... Or some sort of "lid" missing its finial.
But ?

Outer case of an old measuring tape.

I never get bored with seeing those very early designs on relics. That artwork really looks quite old to me, but I'm not an expert at anything

Just zoomed in on pic,should have done that earlier but now what I thought were horseshoes I think are parts of a flower..so now not sure about rosette,could still be or what DCMatt said.
