One more what is it

[Highlander 20026]

looks like a guard for a blade, not a japanese tsuba not shaped in the middle right though

Looks like the guard to a European smallsword or spadroon but unusual, in that it is so flat. Love the crescent. South Carolina was and is big on crescents.

Here is a British 1796 infantry officer's spadroon guard.

A smallsword guard
