Pic is a bit blurry but looks like a '98 model year.Got mine late '97,still going strong.Classic!If you need any more info let me know.I'm pretty sure there's a '98 catalogue scanned in the archive.
Valuation not my specialist skill but if the paint is reasonable I'd say £75 is fairly cheap.I've paid that for a standard M2 Stumpy frame of same era with scruffy paint.
