That's the Rubies fiberglass helmet.
A lot of those tend to be quite warped, from what I have seen. I believe they come from the old Don Post Deluxe molds (or from a remoulded DP deluxe).
You can do a lot better with a 'fanmade' helmet for around the same price, IMO.
EDIT: forgot to mention, the paint scheme is reversed on these too.
