Researcher attributes this mark to I believe Didiere, (opps, France). That's good enough for me. This mark, often but not always seen with the accompanying words "Best fluid steel," are common on graded NIDs. Other then the court case of blown 10 gauge Magnum barrels, I have not found a file reference to Ithaca's barrel suppliers. They bought in the same market as other US makers of the time.
Do you have a file of the late Joe Vorisek's Shotgun Research Newsletter? There is a lot on the Belgium barrel makers within that work. Joe may have been one of the first modern researchers on the subject.
