I copied most of the list below from a 1963 NVA (Nationale Volks Armee) manual on mines and igniters.

MUW , MUW-2

Three-way adapter

Ro fuze serie :

Ro-1 , Ro-2 , Ro-4 , Ro-6 , Ro-9 , Ro-30

If they all came from the same factories then I can save quite some webspace...

Other fuzes :

German mines of the DDR period can be found HERE.

I have DDR grenades listed HERE.
