That's for sure. I bet you would be hard pressed to find two that looked alike. Generally the originals look like they were assembled during an all nighter pub party. The assembly crew didn't have a gram of the experience you guys have assembling stormtroopers. With that said, any replica is going to be an approximation. Even if it's made from a digital scan from the best surviving original that has been laying around for 32 years warping and discoloring. Those Master Replica boys did alright. That's a fine looking helmet for mass production.
Thanks for posting those pictures. It's really cool seeing them all together like that.
