My curiosity finally overcame fears of the hassle of taking my shield down from where it has hung undisturbed for at least a decade. It weighs 15.2 pounds (6.9 kg). I found marks, pictured below, that I interpret as being for Nuremberg. A layer of iron has fully delaminated in one of the images of the back. As I said on my first post: munitions grade.
