I have accepted that 455 mm is the total length. Then I Have calculated all others sizes. It has appeared that a thickness of the barrel is 1,7 mm in the bottleneck. the weight of barrel without rings and the plug is 450 g. I think that 455 is tho only length of barrel but not a total length becaurse barrel can not be such thin and such light. If we will accepted that 455 mm is the only barrel length and will calculate another sizes and weight then thikness or barrel in the bottlenock will be 6 mm fnd weight of barrel will be 2400 g without rings and plags. It will correspond to weight of 2,9 kg if we add weights of rings and the plug. So I think that the 455 mm is toe only barrel length. At calculation I considered that density of a steel is 7800 kg/m3
