To be fair, Hasslefree have basically got you covered on this one. As Avernos pointed out, there’s those two. There’s also these.

Those last two are gorgeous but you might want to wait for them to come out in metal. Now the Assassin’s Creed vikings are heavily based on the vikings tv show (much moreso than actual historical vikings). There’s a lot of partially shaved hairstyles which would be associated more with the Eastern Europeans than the Northern folk.

If you want something that looks a bit more historical but also really cool then Dark Sword Miniatures have this beautiful viking warlord that would fit right in with almost any viking collection. He’s a Jeff Grace sculpt (similar size and style to Tom Meier’s Dark Sword stuff) so he’s more realistically proportioned than most other miniatures meaning his sword is a bit on the slender side.

Alfyn Crowkiller – Wildling

I even painted mine and photographed it years ago with a shoddy camera.

Dark Sword have plenty of other Wildlings that would also fit the bill in their GRRM line.

Mierce do some good vikings, you might want to check their Anglecynn (fantasy Anglo Saxons), Brythoniaid (fantasy Welsh), Jutes (fantasy Jutesd with a beetle obsessed), and their Norse (fantasy Norse with trolls). If you get the Anglo Saxon spearmen (Duguth) in resin the spears have a metal rod inside so they don’t arrive bent. Clearly they put the metal rod into the mould before pouring in the resin.

Here’s a few recommended sculpts.

Both HassleFree and Footsore minis are really good shouts, though you might find that getting duel weapons not sheild and… could be tricky. Might help, but the Nords raiders from Para-Bellum are lovely duel weilding viking models, if you could use the whole box.

Nords: Raiders

Also, for just a big box of mix and matchable vikings try looking at Fireforge games.
