Help with 18 Ponder Shells Case Manufactuer

[derekb]

This morning I picked up a nice "18 PR II" Shell case.

I have managed to interpret most of the marks but would appreciate some help with to identify the manufacturer, whose initials are "CYK", the shell case has a Broad Arrow within the letter "C" which I believe denotes Canadian manufacture.

Thanks and regards,

Derek.

Sorry for the "ponder" - that's what I'm doing.

You are correct with the "C" being Canadian in manufacture,but the "CYK" is proving elusive.

As far as I can make out the main supplier of the CEF was a company called Canadian Explosives Company Ltd using the stamp "CXL" , it's a case of keep searching.
