The problem is the same whether 91, 97, or 95. There are lots of books which cover 18th c French maker's marks, regional and general. There are also several lists of post 1838 marks. But the marks from pre-1838 are only in a few regional books, and one very incomplete general book. Also even if we find you the right regional book, your maker is probably a small worker, perhaps ignored. 91 would be Le Mans,97 would be Niort, both in Western France so they wouldn't explain the Est mark. The round mark could be earlier any numbers visible?
Otherwise you will have to be lucky enough to have someone find this thread who has the right regional bool.
