well, i bought a 1st run single six and it was crazy dirty. i took her apart and wowsers, she was abused. here are some before pics and a few after
mine shows to be made early 1973 which is a first year for "new model" according to rugers site.My Single Six must be a 3rd run, eh? 64-00xxx.
I tested out the mag cylinder for my gun. No function problem, but loud!
