I got this bucket from an artist that I know. It's fiberglass and the parts are resin. I just thought it was a great deal and wanted to share the opportunity with others. I can vouch for him that he's a stand up guy.
He was told the mold came from a screen used helmet but wanted to assure me that he can't verify that and couldn't claim it's veracity. He works more with comic sculpts and his own molds and designs.
The price is right and it's a good looking bucket from an untrained eye.
PM if interested and I'll put you in contact with him. I didn't want to post his site directly here as I'm not sure about MOD rules on that sort of thing.
