out of interest, is it on ebay? there are a few fakes out there. if its the £9,999 one, there are a few things wrong with it. the trouble is, unless it has paper/photo evidence, it's difficult to tell if it is genuine. also, colin seeley sold kits for individuals to build their own. there are no serial numbers as you would find on a rickman or seeley, but it would need to be an f2 within a certain date
