I think what Nate has is as close as you're going to get if you're on a budget; its actually better looking up close. If you're into living history (or aspire to that lofty goal) then you'll probably need to start talking to someone who can tailor and manipulate maille as that's something that isn't mass produced so far as I know, it'll have to be built onto an existing coif, or better yet, a new coif would have to be built.
