Can you provide a photo of the whole figure, including the base? Is there any marking on it anywhere?
Without seeing the base, I will make a WAG and say that it reminds me of the Franklin Mint's Civil War figure series, or the American Fighting Man series, which wasn't issued by FM but was sculpted by the same sculptors, possibly including Ron Hinote.
Another WAG is that the casting originates with King-White/Reeves. I think they had a figure of Farragut in their American Civil War series. This one seems to have crisper, finer detail than King-White was known for, though.
But if you could show a photo of the whole figure, with the base, and the underside of the base, that would be a big help.
Prost!
