Finished her up today.
Total I spent about twelve hours on this give or take.
Gold coat was toned using a mixture of Allclad "polished brass" and black, then I used Naptha to wipe down the surface to give it the antiqued look.
Very suprising, the helmet looks more 'aged' to the naked eye than it does on camera and in direct sunlight - a similar effect the real helmets had I believe.
All in all, I am happy with how it turned out and it was a lot of fun to do and I hope my client is happy with it.
