While it's not the rarest Norton in the U.S., the John Player Norton is one of those bikes a whole generation of gearheads longed for. And while this one is definately in need of some serious restoration work, it looks to be a numbers-matching JPN, though the seller welcomes more information anyone may have on the provenance of the motorcycle.
According to the auction, the current buyer bought the JPN as part of a lot of a few bikes, and its history is unknown. As best the current owner can tell, it features the original fairings, correct rearsets and clip-ons. It is apparently missing the gas tank (which lives underneath the white fiberglass tank cover on a JPN), mufflers, key, a chain and some other various parts.
Though this is definately a work in progress, if this could be verified as an original JPN and not a replica, it could be well worth the time, money and effort it would take to restore it to pristine condition. Are you up to the challenge?
