I have had this shell from my father, it's been with us for ages. On the bottom it reads Part.Fabr. Karslruhe and in the middle left DEZ and right 1891. I think there are not many of these shells around anymore. I hope somebody can tell me about this shell. I'm new to this forum, know nothing about war relics at all. But am curious about this old grenade. I guess they shot most of them, maybe I have the last one? Just kiddin' would appreciate any help.
