I've tried finding a spear to retexture it into the one you requested, but sadly, as I'm not a modeler, I couldn't really find a fitting spear so I tried it with a boar spear and transparency, this is my best shot:
It's not really, good, some trouble with places where you can see trough the model where you shouldn't be able to do that actually
That is very good as it is but, if I may give a sugestion, I think the saxon spear (I guess it have a different name in IR), the one with the wider spearhead, would be more fit for the purpose. You could adapt it the same way you did - and so well - with the boarspear. The original spear is from Ireland, if I'm not mistaken, and it had a golden wired work on the blade, a very beautiful item. Many thanks for doing it, man
. I swear to you, honored blacksmith, that spear will take many enemies on my hands...
