Deletion of Ili River Treaty

Comment: No vote either way, because this looks like just the sort of difficult case that can all too easily crop up in subjects like the more obscure corners of Central Asian history. I am almost certain that the article is not a hoax (though I suspect that the article creator was significantly over-estimating the importance of the subject) - while we are badly lacking in valid bibliographical information for the two cited sources (though the Russian original of the second one, at least https://books.google.co.uk/books/about/%D0%A0%D0%B0%D0%BD%D0%BD%D0%B8%D0%B5_%D1%82%D1%8E%D1%80%D0%BA%D0%B8.html?id=uxsXAQAAIAAJ does seem to have an entry on Google Books), the author, Yury Zuev, was apparently a respected academic in an appropriate subject, it has already been mentioned that Turkish Wikipedia provides another source (and even if Lev Gumilyov seems to have held some distinctly y views, I am currently not seeing how they would have affeted his reliability on this specific subject), and yet another potential source is mentioned, though not fully specified, on the article's talk page ({{ping|Nedim Ardoğa}}, I know it was a long time ago, but do you remember the details? or anything else that might help here
