That was the “special order given sn” part BSA. Rule had a documented SG in that same serial range.
Ask for some pics of the underside of the barreled action. Also it doesn't have a jeweled bolt, extractor, and follower. You notice how he doesn't show a good pic of the front sight. It should have a gold bead. It should be stamped with a backwards S on the bottom of the recoil lug and also "Super" on the underside of the barrel. As always, some of you guys can pretend its original, while i have my serious doubts. One of the reasons bobin said he didnt even deal with the supergrade model. Way too much counterfeiting going on. My smith always warned me. Saying, "if he could counterfeit one, anyone could". Buyer beware. Also a little documentation goes a long way.
