It's a 1995. Not the original fork. Hard to price really, £500 - £600 tops?? Given the amount of nice more modern stuff out there for not too much cash this will only appeal to a die hard collector so you might strike lucky. Best way to test the market perhaps is stick it onto Ebay auction with a sensibly low starting bid and set the reserve for what you would like as a minimum (e.g. say £600), and that will tell you what the demand is.
