Wartime No5 Cleaning kit brush?

[Flying10uk]

The No4 rifle had/had provision for an oil bottle and pull-through stored in the butt.

My understanding was that the cleaning kit, in the tin, was originally intended for the No5 rifle because there was no provision in the butt of the No5 rifle for storing the oil bottle and pull-through.

So are we saying that the cleaning kit in the tobacco style tin was originally intended for the No4 rifle, not the No5 rifle?
