ID of a grenade or mortar projectile or submunition

[EOD]

Gents, I took this image about 13 years ago in Germany when photography was still an analog business for me (and most others).

So far I was unable to ID this item. For size reference I left the surrounding items in the image as they are well known.

Any idea what this item is?

Please, no ideas?
