If I bought it I would look and price it as a custom built on a pre 64 action. Great cal. Im willing to bet it has a fantastic Lothar Walthar barrel. I also doubt it was built to pass as a factory counterfeit, just a nice custom using the original 'dog knot 'profile. A lot of smiths do not like Lothar Walther as they are so hard and require a special technique to work. I have used,shot 2 of theses barrels that were hummer accurate, limit factor was nut behind trigger. very best Winpoor
