I was mistaken, it's not the 50th Anniversary Flattop. It's a Lipsey's exclusive .357/9mm Flattop. Where I made my mistake is when I went to buy grips for it the only grips that would fit were for the 50th Anniversary model or the New Vaquero model since it has the XR-3 grip frame. My thanks for clearing that up for me. I don't know how to post a pic in here yet so here is link to the Ruger in question. http://www.lipseys.com/itemdetail.aspx?itemno=RUKNVB-34X
