Relic gurus please identify this CoRe find

Found this today at an old house. It measures looks like 1.75" in diameter. The back has a stud and directly across on the other side there a long bar like thing that may be for the pin to be fastened, but I'm unsure. There was no pin attached.

Bridle Rosette. There would have been one on each side of the bridle.

Thanks, I found another just like this one around 2 1/2 years ago in an old site.

I would say it's CW so a good find.

Rossette...

looks WW 1 era....
