Thank you for the wonderfully clear photos of both your purse and the marks.
Trev has nailed it for the maker. The firm had another mark, the “obus,” used until 1920, so this is an indication of the working dates of this manufacturing jeweller. The obus mark was used for export silver below 800 standard. See Tardy, 20th ed., p. 206 for more info about the obus.
The 3 other marks are indeed the boar’s head, the mark for small objects made of at least 800 standard silver. You have the mark on both sides of the frame, as it should be.
For makers registered after 1878, see the French Ministry of Culture website. http://www2.culture.gouv.fr/public/mist ... 4%24%2534P
