Camp found ring

A gold plated ring was found amongst hundreds of Union and Confederate camp equiptment items and other artifacts. I'm trying to determine if it is civil war, on the inside of the ring's band is a trademark. The trademark is very small, but it looks like it has two arrows pointing inward at an eagle's head. Has anyone seen or heard of a civil war era jewelry trademark that looks like that.
