The Sweeney Mask

Hi everyone just wondering if anyone knows anything about the masks that were used in The Sweeney film. I've done some searching and can't seem to find anything. Just think that they look really awesome & wouldn't mind getting one. Any information on who makes them etc would be greatly appreciated.

Here is the trailer The Sweeney Trailer - Tactics - YouTube

& here are some stills of the mask...
