Mind you that by the time US squeezed Russi balls to stop CVD-1 engine knowhow transfer under guise of MTCR (When USSR was down and out on floor), much of drawings had already been transferred. It will be reasonable to say that ISRO used that as reference material and added their own genius to make it much better than Russi original. One might have noted how the cryo was uprated to higher thrust for initial burn, during teh boost phase (later it was throttled back to normal thrust (once the craft was off regime when there is effective ISP loss due to gravity). Something that ISRO pressed on, and Russi added that and certified it for all 7 cryos. Out of work freelancign boris were reported used for janitorial work. <img src='http://www.india-forum.com/forums/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='

Also interestign to note that ISRO's GSLV will be 20 tonne thrust C25, and will be fight tested much before IIRC Russi Angara with similar thrust cryo stage. One may ask who is copying who, and possibelity of collboration or even reverse know how transfer in design phase (machining, metallurgy, fabrication capability and experience is much more up Russi belt. Russians have till date not launch a single rocket with LH-LOX cryo engine.
