trolling? lol
Look at the pics i posted..they were taken either during or around the same time ESB was filmed..those shots it looks pretty grey to me.
The video you posted is recent .Pics from CIV it looks green as well...so anything after that it will likely be green. Again..this is speculation...but i think it was replaced at one point and it is green now, but during filming it was smoke/grey. Been trying to find a screen cap during filming to confirm, but its near impossible. All the pics from CIV or other museum tours are more recent than 1979/1980. Its very plausible that the visor was replaced between 1980 and now. It could have been broken or damaged at any point. We all already know there is more damage on the helmet now than was originally put on the helmet in 1979, why would it seem far fetched that the visor was damaged and replaced?
