Question regarding target Ross MkII, no star markings

This Mark II, no star with Mark III rear sight was made in 1909 and by stock markings, issued to the Canadian Rifle Association. Can anyone help by further identify the associated stock markings? 252/R A/ 24? Is 252 an association number and 24 an inventory number? Or vice versa? W7 . 10 (Winnepeg 1910??) This appears to be on of the Ross rifles loaned to the Canadian Rifle Association for target shooting and familiarization with the new service rifle.
