Gorham Tally Mark?

[terrdave]

Thank you to this site for the Illustrated Silver Glossary section, which can be accessed here, or from the top of the page under Resources. We have researched the term Journeyman's or Tally mark. Is the CS (?) on this Gorham Sterling bright-cut Chrysanthemum (1885) berry/casserole spoon termed a Journeyman's or Tally mark?
