That looks like a very good find indeed - it looks like a nearly complete two part buckle set, missing the right side strap guide . The
buckle experts will set you straight on this soon enough !
I am by no means an authority. That looks like an Eagle and Wreath civil war belt Buckle. Actually only half of the buckle. That is one great find. I would go back to see if you can find the other half. That would indeed be a great find. HHHH
I found one online that is like yours, not a true 2 piece wreath. It stated this was a 1905 buckle but no idea how accurate that is although I would guess early 1900s. It's definitely post Civil War. Is your back like this?
Great find! Naval false two piece. I never thought much about belt buckles until I found one similar to yours this year. Congrats! Hope to see it cleaned up!
Can you get put photos of the back up? and also maybe more clear picture of the front. I want to check something out too see if this is the CW period buckle...
