Engines's operational manuals

I’m looking for engine’s operational manuals, particulary postwar jet engines. My interest are soviet postwar military jet engines, but anything is welcomed too and in any language. If you have anything in electronic form (PDF, JPG, DJVU etc.), please contact me on email z(DOT)kussior(AT)atlas(DOT)cz or icq 172998940. Maybe I can offer some electronic documents and also manuals about aircrafts in retaliation.
