Raimey, per Baron Engelhardt, the gauge in a circle didn't indicate 65MM chambers. It simply indicated what size shells you use in the gun. Or, if you will, the size of the chamber. I had a 30's era Sauer 20ga: 20 in a circle to indicate the shells I needed to buy, 19 not in a circle indicating the true bore size. It was a 2 3/4" gun, and that was stamped on the extractor luggers. (A&F import, expect it would have been marked 70MM if made for the European market.) I think the lack of 2 3/4" or 70MM is what tells us it has 65MM chambers.
