Grenade parts

On the battlefields is a lot of grenades laying around. I tend to leave those live ones untouched, but parts of detonated or destroyed grenades I like and usually pick them up. All of these first ones is found on different sites in Kurland.
 Parts of a Gewehr grenade (rifle grenade)

Fragmentation sleeve for the german M24 stickgrenade.

Head for a M43 grenade. It looks like it has a smooth fragmentation sleeve slipped on.

Release arm for the Red Army Rpg40 grenade.

Part of a M24 found in the Norwegian forests.

Strictly speaking not a grenade, but a mine. The Stockmine, or concretemine. From Latvia.
