Photos could be better but I don't have a light box built yet.
I just picked up this Model 15-4 at a gun show 2 weeks ago here in MD. I think maybe someone had some work done on this - in double action, it's as good or maybe better than my Pythons.
I bought this Model 28 from a guy at work who was heading off into the sunset (to New Hampshire!) and didn't want to take all his guns with him. Yea for me!
