It's definitely thin. I was told via another form that is was a model 1874 officers buckle that was missing the back part. By itself there is no way it is strong enough to be a buckle. There was definitely nothing else around it or in the hole.
I like it either way. Does anyone know if they were made in two pieces.
Some of the pictures online seem really thick and some have the same appearance. But pictures are hard to judge.
