It would have to a have great price to travel 500km for that one. Of, course not knowing where you are at doesn't help since we don't know what kind of availability you have where you are at. It has a New Zealandacceptance stamp on the stock. It appears to have had another serial number place on it above the original. It's been around.
If you were making the trip anyway, I'd say check it out but, again, it would have to be a really great price to get me to go that far for it.
Good luck.
