Please, please, please do not mix LOTR stuff into ASOIAF mods, that goes together like s*** and strawberry shortcake, Martin barely touches on fantasy, Others have appeared all of three times over the course of five books, even Valyrian steel weapons are described as looking mundane and ordinary (if not duller than bright steel).
As much as GRRM has said he likes Tolkien, face it people, he's the anti-Tolkien - not a single woman is raped in LOTR (or even made love to gently), while it's, well, constant in ASOIAF, and not only happening to women.
Plus the Clansmen of the Vale are essentially wildlings, any armor they have should be fur primarily, leather, or bit's of stolen, dented steel. They're not stuck up in the mountains smithing, they're stealing each others goats and burning out and off their own eyes and fingers respectively for kicks.
