You probably already know this but just in case -- The Ultimate ESB Boba Fett Project has some partial pictures of the top. It's under "tutorial" at http://www.starwarshelmets.com/ Nothing dead on, though.
Old post, but I've just gotton to this point and realized I could use some more pics of the top also.. I have all of the ref pics on this site, but I don't have the ones listed above.. I've done searches on every search engine I could find for the filenames but came up with zip.. can anyone help?
