Militia Order 213 from 1907 is the documentation used to substantiate the date in which the C Broad Arrow was introduced. I own the 1913 Pattern Entrenching Tool/Water Bottle Carrier and as per military labeling practices, the 1913 stamp is the the year of manufacture and not the contract year or pattern year.
If you look at SWW 1937 Pattern Web, you can find Canadian dated manufactured items with stamps from 1940 onwards which obviously are not the pattern year. Attached is a photograph of a 1910 dated Oliver Dismounted 1898 Pattern leather Waistbelt with a C Broad Arrow stamp.
