While cleaning out my garage this weekend, I found a box from my grandmother's house. In this box is some sort of badge. I know nothing of it, or how old it is, maybe someone can help. It is 2 rifles crossing each other like an "X" and at the top is the "&" sign. It may be brass, I haven't cleaned it up yet. There are no markings on it.

Any clue is very helpful,
Christy
