I remember looking at it many years ago. The bottom was open and the inside of the shell is completely empty.
The fuse is another question. But I know that grandpa told me the thing was completely deactivated.
He was an officer and had a lot of years of active war duty on his shoulders, so I guess he knew what he was talking about quite well.
But I’ll look at it again as soon as the chance arises.
Also to see what we have there.
