This is a bit late, but this past week I found out the characters names in Poland, although not really who they belonged to. I also discovered that there were bumpers about the characters in Poland.
Okay, so I found this long essay and a book online that claims a company called "Ostra Delta" created the identity package, although neither of them are in English. Here's the book since the essay is a download: books.google.ca/books?isbn=9990508062
