I can't give you a clear answer if Miroku made the shotgun or not. However, may I offer a comment. Miroku has made shotguns for 150 years. From all I can gather, they are a high integrity organization and have made high quality guns for companies like Ithica, SKB,Weatherby,Charles Daly and Winchester. If you have a gun made by Miroku, I don't care what company has its name on it, you have a fine gun. Excellent design, fits and finishes. Durable and dependable. Sleek and good traditional looks. Good hunting.
