i know it’s not the same at all, but if you just want a realistic looking one, the “black series” helmet that came out a couple years ago is great. Even has detail on the inside and battery operated sound effects! I got mine when it was discounted to like 50 bucks at wal mart, but i think you can find them at about the retail price online. https://smile.amazon.com/Star-Wars-Premium-Electronic-Helmet/dp/B072QN51ZG/ref=sr_1_2?keywords=black+series+vader+helmet&qid=1567960610&s=gateway&sr=8-2
