Canadian WW 1 B.Q.M.S. Insignia

[midsm]

My Grandfather served in WW 1 in the C.E.F. with his last rank as the Battery Quartermaster Sergeant. I have the Sergeant stripes and some King's Crown metal badges included in his military items.
I'm trying to find out if the stripes and the crowns would have been worn together to signify him as BQMS, but information seems sketchy. I have found that the guided crowns were used before the crown patch. Any help would be greatly appreciated.
