Just received the project gun form Mr. Andy Horvath. Sent him the gun and parts pictured below which was, and still is I suppose, a 4th Generation of the 200 that were made NR4-FL series Single Six. When Ruger and their distributor did the 500 stainless steel 3 & 3/4 inch convertible single sixes I thought they kind of missed the boat by not producing an all blue model. Got tired of waiting so decided to have my own done, very happy with the way it turned out.....The grips are a pair I had made by Lone Star Grips back in 2014, buckeye burl. Don't know if I like them on this gun or not, may go looking for some more exotic wood, or maybe some horn of some kind.
