I assume this to be a recent (Asian) reproduction. Multiple people with different items that all have the same mark up for ID in a week’s period is very peculiar (I know that you also asked in the eBay PGP frorum, I am refering to other people).
Evidence for my theory: formerly unknown and undocumented mark. All have inset bases with a slight reddish-brown scuffing on the left. All have the same ‘hand painted’ text blurb in French at EXACTLY the same position and without the slightest change in writing.
The same goes for the ‘flow’ of the blue swords mark, the blurring is exactly the same in all cases. Cross-layering of images with partial translucency shows an EXACT match.
Manual work would result in minor changes in both, but the result here points in direction of industrial (mass-)production. Hence repro, as even the “writing” in gold is not real, but printed.
Image #1 (yours), followed another example (#2), finally an overlay (#3) of your base on the second item:
