RARE Vintage Photo Frame possibly from WWII or Civil War era

This is a Vintage Mini Photo Frame possibly from WWII era, considering the photo of the soldier's leggings. Google Lens states it could even be Civil War-era handmade copper frame possibly given as a gift from the Grant family. No stamping on the backside, so may have been something made by hand, rather than machine, but not certain. I've only found one other similar that has crossed sabres on it in place of the cannons. Finish appears to be copper, but again, not certain.

In good working order as far as the hinged stand. 2 1/4" x 2 1/4" in size. Would make a great addition to your Military memorabilia and a good talking piece with your friends. The one pictured is the one you will receive.
