Unknown Manufacture markings Canadian or U.S. ?

Does anyone know what companies these are and where ? I don't know if these companies made projectiles and or just casings so I will repeat this
on the Cartridge section.

Gordon,

I have one of the codes in my list, but no idea if they made projectiles and/or casings

C.C.Co : Clinton Cartridge Co., USA

Hi Gordon, my understanding is that all of these monograms are attributed to Canadian Cartridge Co.
They are usually depicted as concentric letters on cart cases.

Tim G(uru) may be able to set us straight.
