I also happen to think the Soviet moon project was about 80% complete. No showable results, though - which allowed to deny the very existence of the project - but at least the hardware heritage is still there in the flying systems.
You're talking about NK-33s being used by Orbital Sciences?
Yes, but also about Blok-D - the fifth stage of N1-L3 stack - being used on Proton and Zenit today for launching telecom sats to GEO, and also about Soyuz spacecraft - which got a lot of development in preparation for Moon flights.
