I actually work in Hertfordshire, and live in Luton
I have posted a thread with a link to this on the RPF (replica prop forum)' for more info as there are loads of builders over there.
My opinion (i havent studied HIC a lot mind) is that this may not be screen used for production purposes, but is a possible first generatiin cast from the screen used one. This is my own thought but lets see what the RPF have to say. Unfortunately, the paperwork/provenance has to be from someone with a direct link to the film, and auction houses made many errors in the past. 2002 was in the SW boom years, and people put their name to and forged anything to make an extra few quid. Im not saying its not real, because i really hope it is, but this would be one of the most interesting finds after the guy who found a screen used ANH trooper costume in his loft which was given to him by a friend of his parents who had worked on the movie.
