The Western banner 4 is a reward from completing the elite Western Provinces Diary. The armour is received from the Elder gnome child at the Tree Gnome Stronghold, and can be retrieved from him for free if lost.
Strangely enough, all 4 of the western banners have higher stats than the wilderness swords.
