My thoughts too. This lady is selling 3-4 bikes and I'll be checking it out tomorrow, but I wonder what else is not original. Also the rubber boots over the stanchions don't seem to in the catalogue's pictures.
Only the frame and the fork were original. It was incredibly sad to see how this bike was stripped of the only thing it had going for it - the XTR groupset.
But I shouldn't be surprised, there a couple of threads including one here suggesting "a waste of components": viewtopic.php?f=1&t=223464
It's just not right... All the bike needed was a modern rear shock, or as others suggested "winding up" the existing one.
It's just a bike I known, but it broke my heart to see such travesty
