The German WWI egg-handgrenade in its three stages. This is the 1917 version of the egg-handgrenade, with the band around it for better grip.
Left:
On its way to the front with the transport screw and gasket. The intact gasket is not commonly seen as it will have crumbled away, but here it still is.
Middle:
At the rear trench the transport screw has been removed, and the grenade has been fitted with a friction fuse. This is how it will have been carried forwards to the front line trench, ready for use.
Right:
After use. First boom, and then the fragments fly. This is a rare and unusual find. The rare thing is to find an exploded grenade that is practically complete, as the fragments usually scatter over a large area. This one, however, exploded inside a bunker, and was recovered in the mid 90s in France. So, this is what an exploded egg-handgrenade looks like.
