Must be from the same “maker” as the other 2. I do not think it is a period piece. Again take them as non expert thoughts- just another collectors opinion.
Looks like it has a chance.. But the closer you look,,the more you see. The Devil is in the details. The cartouche would have hand done dapping to hold the eventual enamel which it doesn't. Inner band looks smooth but when you look to the sides you can see some faults / pitting.. Another to let someone else get..
It is not possible to determine the period of manufacture of the runes, IMO fake
