This is something I've been working on for few weeks. Now with the passing of Ralph McQuarrie, it seem like the right time to post this.
We have all seen photos of the McQuarrie Boba Fett concept helmet. Skygunbro made that helmet a few year back. The animated version of the Fett concept helmet appeared on a few episodes on the Clone Wars.
I've taken three names to come up with the Mrk-1 title.
K-Obi Wa Kenobi
#1 (my first helmet build)
I started the build with WOF's Fett helmet template to made the done. Back filled the dome with ridged expanding foam. Pealed off the paper template, applied bondo and started sanding and filling again and again.
