The left hand case was made by the Canadian Motor Lamp Company, Windsor, Canada. (CL/C).
On inspection any 25Pr cases manufactured by CL/C were meant to be replaced by new cases - I seem to recall a story that one of their 25Pr examiners hadn't been trained and as a result a large percentage of the cases hadn't been inspected properly, leadind to them being condemned.
Unless it is very faint or obscured by corrosion, this case doesn't appear to be stamped CF.
The right hand case was manfactured by Robert Mitchell Co., Ltd. Ville, St. Laurent. (RM/C)
Both primers were manufactured by Beatty Bros. Ltd., Canada, (BB/C) filled by Canadian Car Munitions Ltd, at Cherrier (CR/C)
The Boxed 'E' stencilled on the side of the case denotes thy were filled Cordite W or WM in cord or tude.
