Well, as I said "France is not my cup of tea" I am unable to discuss French marks deeper. Anyway, I managed to find the Lyre-mark in English Tardy on p. 130 and in Divis #1732 on p. 205. Both with the same text. I see no reason for doubts, it is the same mark. About the lower, presumably, maker's mark, I have no clue.
(Don't overdo it, it's a lyre) ;-))))
