Thanks a lot! The quality is very good, only the pages are somehow illogical. 
This is a rare animal. I was not immediately able to find documentation for it, and only one Russian source has it. Unfortunately, there were no others. Now I looked - yes, the sheets are somehow scattered and there is no schematic diagram. It was probably large and was printed on a large sheet that was being rolled up. They couldn't scan it or lost it.
