Thanks for these informations.
Pisis: thank yoy. All avaible by google I do have, there is not to find anything actual. The Ritterkreuztraeger dont know him, some of them wrote me som time ago, one of them told me he is dead.
Adler: thank you. I registered as a member of this forum. The only in this forum is the list of the "tankkillers", where he appears.
Anton Korol was my uncle, we lost contact when I was a child. Some time ago, I heard he has gone to South America (Paraguay), thats why I wrote in Spanish too, hoping to find a response from people in Argentine or Paraguay who may have known him.
