just got this absolute beauty today 
looks like Aug 1940 is date of manufacture, but can anyone translate text (guess Serbo-Croatian) on cap? tried to scan on Google Translate app but no joy...
also, did the 'spike' on the cap have a role in activating the grenade? I'm guess you poked that in the hole exposed when cap removed to initiate the delay?? or maybe you just struck the head on something hard as with other percussion fuzed grenades??
I understand these were used by Yugoslav partisans and also by German forces in WW2.
