Here are a couple more. The 2cm round pictured is one of literally hundreds that littered the ground. Most of what I found were 2cm projectiles seperated from the shell casing by the explosion. There were tons more that stayed together, but I thought it too risky to bring back. Notice the intact primer on the 2cm casing and how the neck is deformed.

Nomenclature on the 2cm round fuse can be seen. "1943 waffenamt 2cm", while the the manufacturer code and what type can be seen on the reverse. The same is true on the shell casing's base. The other casing is that of the .50 cal. Mike
