Help with buckle ID

[Vertigo]

Long time lurker here but I'm posting for a friend. He found this buckle today in Southeastern Connecticut and we're trying to ID it.

Possibly British, Canadian, maybe even CSA? Any help would be most appreciated!

Lots of civilian/Govt uses, including some military but yours is circa WWI. (Navy being one)

Nice Civil War Snake Buckle, I agree with AARC / goldnugget

I am pretty sure that is post Civil War, as they had heavier,solid belt loops instead of split wire loops.
