Without the advantage of a full hallmark it's difficult to be certain. However the most likely identification in my view is that C.C is Colen Hewer Cheshire, a silversmith whose premises were at 3 Northampton Street Birmingham. He registered this mark at both the Birmingham and Chester Assay offices but it is not a Chester mark because his registration occurred after 1 May 1890 when duty ceased to be payable. So, assuming it is a Birmingham mark of C H Cheshire, we can assign a date between 1867 when his Birmingham registration happened and 1890.
However we have to sound a note of caution as there is only a partial hallmark present. This should not happen without the full hallmark or at least the remaining parts (anchor for Birmingham and date letter), being stamped on another part (hence Trev's earlier question). Possibilities are a hallmarking error or a replacement part.
