Hmmm, you might phone warhammer world, funnily enough. They have one on display upstairs in the museum, unbuilt, inbox etc. This is of april 2009. They might be super super nice and scan the instructions.
Be warned though, it is a bitch to build. It's so heavy I heard of people designing internal support structures so it didn't fall apart but there may be better methods 15 years after the fact. The built version I saw was held up by a re-purposed record player's needle arm. A fat solid metal one. You may also consider admantium as an alternative
I remember the advertisement in the journal said "You'd have to be mad or American to buy this". Back in the good old days before the suits shived the journal.
Out of curiosity, are you at liberty to state how much the classic goes for, in comparison to the new
FW one?
