So I have seen this miniature before- you can find it at here. Scibor makes it, they are a Polish company and I actually own a few of their models for my Space Wolves army.
Some players don’t like playing against non-GW or Forge World models, which is somewhat understandable. My counter argument would be this exact model- take a look at the GW model... …then by all means look elsewhere for a suitable badass like this.
