18 Pr Manufactures mark ; who exactly and where ~

[Gspragge]

Exactly who are these and where were the factories, not rare markings;
CC Co (Canadian Cartridge Co) and CCS - similar and of the same time periods.
Can some one clear this up ? Stuff I should know :tinysmile_cry_t:

 

[Snufkin]

Both cases have variations of monogram used by the Canadian Cartridge Co. of Hamilton Ontario. The Canadian Cartridge Co. was one of the largest, if not the largest, Canadian supplier of 18-pr and 4.5" cases during WWI.
