Off the top of my head, they look like post-WWII Russians, or East Germans, to me. Especially the shape of the helmets, and the firearms, look like they depict East Germans. I wonder if these were made in East Germany? Lineol was located in what became East Germany, and I think they continued production after the war, switching from composition to plastic. I can look in my books to see what I can find.
Prost!
