^^^ If it's the original group and the dates match the frame I would have a hard time passing. If it is not original and newer I would point out and get the price down or just do FF. Many think frame and fork separated are best way to sell for the most money but original with bike says a lot to me. I think it adds a value above just part out as they are not easy to come by.
And why not take a magnet, first year could be the unobtainium titanium. I have yet to find any but hope someone here does at some point. At least unbroken.
