I am seeking loss data for a JU52 shot down in the Stalingrad airlift. I have photos depicting aircraft G6+E_, with the last letter not visible. The E is a lighter color - not red.

I have narrowed the possibilities to:
KGrzbV102 - G6+EN, G6+ER,G6+ES
KGrzbV105 - G6+EX, G6+EZ

One of the crewmembers was Wilhelm GOELLER (or Göller).

I appreciate any info anyone may have.

thank you
