There is a mention of it being for sale on the BBC site http://news.bbc.co.uk/newsbeat/hi/entertainment/newsid_7530000/7530845.stm
and this seller seems to have all the other items mentioned so it seems genuine, personally I think it would be cool to have the Holy grail but even that's out of my price range, there are also some star wars bits an original tie fighter model, a head cast of one of the cantina aliens and C-3PO's feet.
