Morning Walt. I reviewed the Dress Instructions file for the RCCS and Cadet Services.
Reviewing the organization of the RCCS, it was noted that the militia component of the corps was designated the Canadian Signal Corps from 1913 until 1921. The abbreviation C.S.C was in use until 1922. At that time the militia designation was changed to CC of S. (Sorry, typed wrong abbreviation, it should be as reads, not CC of C.) There was no record of a metal shoulder title being authorized for that designation. The C.S.C. titles are reported to have been worn by the CEF Signals contingents.

There was no specific metal shoulder title mentioned for Cadet Services until authorized in 1956. It was the pattern that read C S of C. All previous GO authorizing badges for the Cadet Services described a cap badge, collars and buttons but no shoulder title. Of interest the collar badge authorized for Cadet Services circa 1925 was the general service collar badge.

It would seem that the one you have is a Signal's badge.
