Two salts-cellars

[silverfan]

On an antique market I found 2 French salts with minerva premier titre and very tiny lozenge mark. With a magnifying glass I identified the master's initials as C and M with a tree or a flower between, what is difficult to recognize in the photo. Doe anybody know the maker?

It would be useful if you could take and upload some photos of the maker's mark by holding a loupe 10X against the photo of your telephone.

I tried to take a better photo but in spite of many attempts withhout success. So I hope a member will recognize the maker's mark with my explanation of the initials C and M with a tree or flower/plant between.
