I've been away for a while, but just spotted the following on eBay and thought it may arouse some interest: 2K22 Tunguska/SA-19 Grison Manual
I could give it to you for free...
I just realised I already have the manual in .djvu format
*********I have quite a large collection of Flight, Weapon Systems, Tactical & Supplementary Aircraft Manuals for Jets, Helicopters & some Props, spanning the Vietnam era to present. If you're interested in trading Flight Manuals, mainly for modern military aircraft, send me a PM.*********
