The seller says about the wheels "fully original with the exception of new rims and tyres (which are a N.O.S. couple of the legendary Pirelli Stella, widely considered the best tyres of those times), a new set of N.O.S. decals of the very same quality they used originally and a B33 Brooks saddle" so the seller claims to have laced new wheels, replaced transfers and the saddle. Perhaps the paint was good to start with and the bike had some luck.
