I think its most likely second half 19thC. There are a lot of modern good items around but this one looks ok to me. I'd worry about a lack of deeper oxidisation in the recesses between the blades and shaft loop, but Valjhun has seen it pre-clean, so would have suspicions if it had looked newly aged or dirtied up.
I think if it was 'new' it would have an ornate handle to go with it. If it was recent it would be lighter or unsharpened.
I'd have a punt at it at the right price.
I think its either old enough or nice enough to merit a place in my collection.
I like the plain wooden shaft.
Heres a similar shaped head in the V&A
