help ekm

      Hello everybody.
      I have 1 half of a ekm here says
      1./Nebel Ersatz Abt.3 On top it says, 0 177 0
      What i know so far is that the 0 is the soldiers bloodtype...and that 177 is his personal nmr?
      where did they fought? And when? is there a way i can find out who did the ekm belong too?
      did try too attach a pic. But it says files too big.
      thanks in advance.
