While there is always more to be said, I hope that answers (including mine) and links found in the following question threads should be useful:

• Would post-viking era Scandinavian armies and soldiers be organized and equipped any differently than other "western" medieval armies?
• A Question Norse and medieval infantry and weapon/armour choice

Especially answers by /u/Arilou_skiff and /u/vonadler are worth checking (since they know medieval Swedish materials much better than I).

On the other hand, Later Medieval Sweden in fact has a very rich resource on weapons and armors: The mass grave of the battle of Visby in 1361 where the army of King Valdemar IV of Denmark massacred the militia of the Gotlanders. While I had already cited some of its materials in the threads above, you might able to find interesting stuff in the following online resource sites if you can read some Swedish:
