Thanks guys, that was of great help. I sort of had the 1163.g figured out after I weighed the barrels that is was the weight of them. A I sort of thought the 15.3 was the choke of the barrels. The other stuff was really confusing, and I sort of had it read backwards. So thanks again. What was also interesting was that the gun also had a proff mark from the provience of Karnten aside from the two Ferlach proof marks and Austrian proof mark.
