I’ll save you (and everyone else who pulls up the fur-lined items on spidy and thinks they’re going to be rich) a little grief – all of my information points to the fact that the recipe unlock does not exist in the game. You can still purchase the mask/helm/helmet and it has to be one of the easiest puzzles to figure out – the NPC isn’t even in an out of the way location. It’s fun and will feel like an accomplishment once you find out what to do to get these. They don’t sell terribly fast and it generally is only really profitable if someone tries to manipulate the price and you can sell directly to their buy orders to take prices back to natural equilibrium (the helmet on Nov. 27th was great – about 9g profit in about 2 minutes from someones manipulation attempt).
As far as the skins – I don’t know about the mask, but the helm has this furry mohawk-looking thing on the top. The helmet is the same skin as the dry bones armor, which is probably why it is the best seller of the three.
