Go over and check out tk409.com. He has a pattern called "The Mystery Helmet." It's the closest thing to the original I've ever seen. It's what I'm using for my own bucket. kudos to TK409 I used 1/16 in plastic (the same used for gutters) as the base then built up with modeling clay to get the exact look. I'm half way through casting in plaster. I might set up some pics of the process in another thread.
