Zero, I think Sauer (Hawes, Hy Hunter) offered a lot of 'different' special models. And I have seen some with the same model name fitted with different features, usually in the finish. Some with chrome frames, blued cylinders and barrels, and brass grip straps. So other then the 'Western' Marshall being the most common, fully blued one, I don't think there was much of a standard as to how the others were finished. I'm glad you like your gun, I really love mine! Check a couple of the other threads on Hy Hunter, or Sauer (which became Sig-Sauer then Sig) or Hawes, they were all made by Sauer and imported by different people. Enjoy that gun! 44 Man
