Well I posted a question the other day asking about buying a used Python 6 inch blue and getting it refinshed by the factory. I've haggled the price a bit and took it home today to clean it up. After much cleaning it's going to be about an 87% gun. It is solid and locks up tight. Serial number is 72XXX U I'm thinking its about a 1968 or 69? It's only 3,000 digits off from another one that I had. Thanks.
