Upon more in-depth examination of the photos, I believe this is a mix of antique and modern work, containing a piece of genuine, antique chainmail (the upper part) that was completed with some modern additions.

Please have a look at the cropped photo below and you may notice the upper part (red arrows) appears to be riveted and shows significantly more age signs than the lower part (purple arrows showing a very visible difference in oxidation). Also, the lower part, or at least some parts of it, appears to be butted (yellow arrows).

Now the difference in the in the oxidation of the rings between the upper part and lower part may also be because the mail was only partially cleaned. Since the upper part has inserted leather strips, it could not be cleaned the same way like the lower part, thus retained more of its age patina/oxidation.

But then again, better close-ups of the rings can reveal much more.

Other important indicators (besides the joining technology of the rings) may be the thickness of the wire of the rings, the diameter of the rings and the surface quality of the rings.

Any difference in the thickness of the wire and/or diameter of the rings would indicate that the mail was made from two different pieces joint together.

Any difference in the surface quality of the rings would indicate that the mail is made by pieces belonging to different time periods.
