First step, take the popular P-3 style that everyone loves and make a mold out of it. Next, cast the mold with molten iron and let it sit. Finally, take out the cast and flatten it to get that cross-era feel. Now of course its not that extreme, but heres the P-3 style. Made with metal frame, metal hinges, and UV400 lenses.
