Joe, the gun in your picture appears to me to be "chromed' its more white, than 'yellowish' and the factory nickel guns were SC-6s or 5s I believe the ones with adjustable rear sights,,,,'Superior Plating' was across the street from Ruger and they did stuff for them from time to time and when it was done there would be a small white sticker on the end of the box and either say "Nickel" or "Chrome", my wife still has an old flatgate that was chromed, and there was a sticker on the end of the box,,,the box got tossed??? by the owners family and Steve Vogel himself told her there was NO record of it, but if he saw it , he would tell us for sure one way or the other,,,Steve passed away before the Monroeville PA RCA Theme show....oh, she paid $200 for the gun, and the family did recall the box, as I asked them "how did you know its 'chrome"??? I said to them they chrome bumpers and guns are nickeled" thats when they told us about the small white sticker...in this case we bought the story and at $200 who gives a rats patutty........:cool::rolleyes:;)
