If the maker cannot be identified, could an approximate range of dates be determined from the shape of the other three hallmarks?
For instance, do you think this Second Republic, Second Empire, or Third Republic?
Are these hallmarks consistent with the Third Republic?

Hi,
Is it eagle (gold) or boar (silver) head ? Eagle head was used on French domestic gold minimum .750 since 1838.Multiple marks on clasp are applied to prevent tax evasion.Number and position of eagle head correlates to the weight, meaning one cannot get back to the workshop and solder the clasp to much heavier object.
Marks are not very clear;compare with eagle and boar head.
