I was at Elstree props last week and they do claim to have a newly found and original anh Vader mask..
I have found both Elstree props and heritage very genuine and knowledgable on what props they have, there seems to be 2 sides to elstree props 1 side that is a business and the other side to preserve what props have been found at elstree.
There is a contact email on there site so maybe contact them I'm sure you will get an honest answer.
I was lucky enough to see there original c3po head and there ROTJ Luke light saber, the head was appartently screen used but the saber was one of a batch made for rotj but rejected due to an imperfection.
I'm a massive Vader fan and asked about the vader but alas it was in safe keeping BUT I have asked to arrange to go and see this at a later date, if the dream comes true I will go on a picture frenzy.........
Its a sad reality that in my years collecting props we all start to view things with a guilty untill proven genuine approach, trust me i have been ripped off big time in the past.
BUT I HAVE A STRANGE WARM FEELING ABOUT THIS ONE.
