Left: A metal shoulder title for the Canadian Signal Corps. Joe Costello (www.rcsigs.ca) has advised me that there is evidence of this title being worn during WWI.
It is the individual letters of the Canadian Signal Corps separated by full stops between parallel bars. This example is marked 'W M Scully Montreal'.
