From WW1 several cartridges are known for launching grenades.
Starting with the Taube practice (red base and mouth).
With a CWS case without any colour.
One with a green base and mouth.
The cartridges build in the life grenade in the factories.
Also a round is known for firing a rifle grenade.
Now I found one, with a black case mouth and a case made by DM.
I have no idea were it has bin used for.
Any ideas appreciate,
Rgds.
