Wow! Thanks for the lead Drokkul. I've been comparing this one with the Mystery Helmets. Although like you stated, badly recast, I've been comparing and it is pointing in the direction of a Mystery Helmet. What paint scheme do you recommend for this helmet?
Well that's up to you really. Its already done in a very loose ESB style. The MH I believe was molded from an ROTJ helmet but this one doesn't seem to have any of the damage marks (scrapes into the resin) from either ESB or ROTJ (which has a lot more physical damage) but most helmets are like this when cast. It allows the buyer to make what they want out of it.
I am currently attempting my first ESB paintup and there are parts that make me want to tear my hair out! The ROTJ has its own set of challenges, but aesthetically I've always found the ESB more interesting.
I know you stated that you want to get another bucket down the line. Maybe if you are doing a costume or full size display as well at some point think about which version you want to do and then paint this bucket in the opposite style? Then when you get the next one get it for your costume/display and put this one in a display case?
You said you looked thru some paintup threads but go thru the galleries here as well because they have excellent closeups of the original pieces and it will probably help you decide which version you like the most!
Good luck with whichever route you go!
