SRS please for SA 1220. Barrel RIA 11-18. It also has a mystery inspectors cartouch. I haven't found it listed anywhere. It appears to be H?JW followed by WJS, followed by SA over SPG. The grip has 3 or 4 circle P's and a small 75. There's no marking on the front of the stock and no plug from a RB stock. Any information appreciated. Pictures too.
