Crossed Derringer guns pin - military, police, WWI?

[marble]

Here is another figural pin. It shows crossed derringer pistols. The pin is just over ¾" across, slightly domed, and has a stub screw post and buttonhole type screw backing.

Is this a police item? Or from WWI perhaps? I think the backing style would date it to before WWII.

Thanks in advance!

I believe that is military police. Harpers Ferry Pistols

My old MOS! Brought back memories to see that!

With no backing plate it is a officer's.
