Civil War site. Has a rivet fixed to top. Very stiff sheet brass. 2 small holes on back side of sheet metal behind rivet. As a long shot was hoping someone would recognize it as being part of something.
Hi Dan. You got me pointed in the right direction. I started looking up Frogs and from what I see this item appears to be a Scabbard throat. I'm sure it is a bayonet throat as it is not wide enough to accomodate a sword. Just have to try to narrow down what bayonet.
