I have searched the forum and only found this topic concerning the mark from christofle for solid silver used before 1935.
However I think the item in the thread does not show the mark before 1935, as originally stated by the author. Or does it? To me there seem to be two factors. One is the initials (OC vs. CC), the other is the shape of the sourounding (diamond shaped vs. diamond with the corners cut off). This can also be seen in the resources posted later on in the thread. The combination in question by OP is a hybrid with CC but pointy corners.
I have a wine beaker with a mark that has CC and the cut-off-diamond shape:

While googeling I only found one other example of this exact mark on a pair of salad utensils.
Since there seem to be three combinations I am wondering, what exactly determines before 1935? The initials or the shape?
Also, why is this early mark not included in the Christofle Makers' Mark & History page*?
Looking forward to hear some opinions.
