Looks antique to me but maybe someone knows more about it: https://www.youtube.com/watch?v=DohIsvhay0o
I think that’s a different flute. This one seems to have ivory-like rings and a flatter crown. That said, I would also like to know more about that other flute.
The flute with the ivory rings has a number of distinct features which when combined make it quite unusual. The overall styling of the key work looks french, but the way the G# key shank arches over the top of the C key shank is very unusual, as is the arrangement of the foot keys. I haven’t seen that combination on any antique french flutes, even though there are some other stylistic similarities to the key work.
The tone holes also look to be significantly larger than on any antique french flutes I’ve seen. And the styling of the faux ivory rings is also unusual. So my guess would be that it could be a modern “Irish” flute made by a current maker, perhaps based in France. But that is just a guess.
You can see more details of that flute here:
I’ve found it’s often easiest/quickest to contact the player. You could ask in the comments section on the video, or go to the artists website for a contact email address, which is probably the better option.

I’m pretty sure it’s not an antique. To the extent I can see them in the videos linked here, the keys look a bit like some of Tony Millyard’s. 
I’m by no means certain of that! The Keys | Tony Millyard
