Christofle or not?

[Caxalin]

Good day

I bought such a thing,
and a couple of things confuse me
It seems that the dish looks like Christophle, but this rooster, and not a clear brand of the master, on which the last letter is D or O, and in the corners it seems like numbers 4. And 15 more, which is closer to silvered, and the rooster does not look like the stigma of silver.
Who can put an end to the search
Thank you for your answers

Hello, most likely French plate marks. The rooster does not look like the one for Christofle, neither does the mark on the left hand side look like a Christofle mark. No clue though as to who the maker is, sorry. Regards, Bahner
