Technical manual from IL-76 ИЛ-76

Hello,
I am from Austria (Europe) and I am writing a book about the aircraft Iljushin-76 ИЛ-76. So I am looking for a old technical manuals or technical hand books from the Iljushin-76 ИЛ-76. The technical manuals could have technical descriptions from the cargo compartment only and how to load and unload crago in and from the cargo compartment.
It could be also old used manuals, that would be no problem and it could be written in russian language. I will try to translate it.
It would be great if somebody could give me an information or could make me aconnection. But I can only communication German and English, not in Russian language.
