All I can think of is that the x-ray tester made a mistake. I had the operator shoot the machine at the muzzle of the hackbut to stay well clear of the small iron pieces nearer the breech. He shot several other objects I had, all either iron or steel, and the results on all of those seemed quite reasonable. I'm wondering if he had to change a setting on the machine to get a correct reading for a nonferrous object, and didn't do so? I didn't tell him the hackbut wasn't iron like all the other things. I'll have to ask him during the coming work-week.
