yeah there are. do a quick google for heart buckle cover, just did one and a bunch came up. didn't bother to check much further because of the amount that popped up so i suppose it could be misidentified. But 99.9 percent sure from judging by others I have found and that quick goggle search that yes it is a buckle cover.I found a buckle cover a few years ago that was different than this piece. The other one is one solid piece. Are the different styles of buckle covers?
You are correct. Forgive my ignorance. I am wrong.Traveller777, I intend no offense in responding with the following information. You're giving us proof that finding that type of buckle-cover/buckle-shield "in a Confederate camp" does not mean it's from the civil war. That type (stamped-brass, and usually with a raised emblem) was invented and patented in 1892.
The patents for both the stamped-brass (1892) and the solid-cast brass (1879) versions are in my reply to Squirrel322 below.
