@SDC thanks for the reply. I remeasured with a ruler and your measurements of the case are pretty spot on. It definitely has an interesting history. I was in the Marines as an Ammunition Technician and having an awesome round like this for me is just phenomenal. And a another question for everybody, has anybody seen anything like this before? I have looked around the internet and only found one other piece of trench art like this. And also if you have one I would like to know what kind of round it is and what you do with it.
