I have a Christofle silverware with a number, I am tracking down.
Riding the web I found those serial numbers, in Christofle's, are unique for each article, even when the tradition sets them for a whole batch. I also read that nobody knows the code, no record exist and probably never existed, about Christofle's serial numbers meaning.
Do you know about that ?
The pic corresponds to a serving tray, marks are hard to read but it is a Christofle from late XIX to early XX century.

Ty !
