"German Silver" what %'s of tin and other metals are in this alloy?

Question

I need the proportions in percentages of the different elements.

The term itself is a misnomer it does not contain any silver. It is a turn the century early 1900's term. The exact chemical formula would be cool too. Easy 10 points. !

"Many alloys fall within the general term of "nickel silver". All contain copper and nickel, while some formulations may additionally include zinc, antimony, tin, lead or cadmium. A representative industrial formulation, Alloy No. 752, is 65% copper, 18% nickel, and 17% zinc."
